Abstract

The Concise Guide to PHARMACOLOGY 2019/20 is the fourth in this series of biennial publications. The Concise Guide provides concise overviews of the key properties of nearly 1800 human drug targets with an emphasis on selective pharmacology (where available), plus links to the open access knowledgebase source of drug targets and their ligands ( www.guidetopharmacology.org ), which provides more detailed views of target and ligand properties. Although the Concise Guide represents approximately 400 pages, the material presented is substantially reduced compared to information and links presented on the website. It provides a permanent, citable, point‐in‐time record that will survive database updates. The full contents of this section can be found at http://onlinelibrary.wiley.com/doi/10.1111/bph.14747 . In addition to this overview, in which are identified Other protein targets which fall outside of the subsequent categorisation, there are six areas of focus: G protein‐coupled receptors, ion channels, nuclear hormone receptors, catalytic receptors, enzymes and transporters. These are presented with nomenclature guidance and summary information on the best available pharmacological tools, alongside key references and suggestions for further reading. The landscape format of the Concise Guide is designed to facilitate comparison of related targets from material contemporary to mid‐2019, and supersedes data presented in the 2017/18, 2015/16 and 2013/14 Concise Guides and previous Guides to Receptors and Channels. It is produced in close conjunction with the International Union of Basic and Clinical Pharmacology Committee on Receptor Nomenclature and Drug Classification (NC‐IUPHAR), therefore, providing official IUPHAR classification and nomenclature for human drug targets, where appropriate.

Introduction

In order to allow clarity and consistency in pharmacology, there is a need for a comprehensive organisation and presentation of the targets of drugs. This is the philosophy of the IUPHAR/BPS Guide to PHARMACOLOGY presented on the online free access database (https://www.guidetopharmacology.org/). This database is supported by the British Pharmacological Society (BPS), the International Union of Basic and Clinical Pharmacology (IUPHAR), the University of Edinburgh and previously the Wellcome Trust. Data included in the Guide to PHARMACOLOGY are derived in large part from interactions with the subcommittees of the Nomenclature Committee of the International Union of Basic and Clinical Pharmacology (NC‐IUPHAR). A major influence on the development of the database was Tony Harmar (1951‐2014), who worked with a passion to establish the curators as a team of highly informed and informative individuals, with a focus on high‐quality data input, ensuring a suitably validated dataset. The Editors of the Concise Guide have compiled the individual records, in concert with the team of Curators, drawing on the expert knowledge of these latter subcommittees. The tables allow an indication of the status of the nomenclature for the group of targets listed, usually previously published in Pharmacological Reviews. In the absence of an established subcommittee, advice from several prominent, independent experts has generally been obtained to produce an authoritative consensus on nomenclature, which attempts to fit in within the general guidelines from NC‐IUPHAR. This current edition, the Concise Guide to PHARMACOLOGY 2019/20, is the latest snapshot of the database in print form, following on from the Concise Guide to PHARMACOLOGY 2017/18. It contains data drawn from the online database as a rapid overview of the major pharmacological targets. Thus, there are many fewer targets presented in the Concise Guide compared to the online database. The priority for inclusion in the Concise Guide is the presence of quantitative pharmacological data for human proteins. This means that often orphan family members are not presented in the Concise Guide, although structural information is available on the online database. The organisation of the data is tabular (where appropriate) with a standardised format, where possible on a single page, intended to aid understanding of, and comparison within, a particular target group. The Concise Guide is intended as an initial resource, with links to additional reviews and resources for greater depth and information. Pharmacological and structural data focus primarily on human gene products, wherever possible, with links to HGNC gene nomenclature and UniProt IDs. In a few cases, where data from human proteins are limited, data from other species are indicated. Pharmacological tools listed are prioritised on the basis of selectivity and availability. That is, agents (agonists, antagonists, inhibitors, activators, etc.) are included where they are both available (by donation or from commercial sources, now or in the near future) AND the most selective. The Concise Guide is divided into seven sections, which comprise pharmacological targets of similar structure/function. These are G protein‐coupled receptors, ion channels (combining previous records of ligand‐gated, voltage‐gated and other ion channels), catalytic receptors, nuclear hormone receptors, enzymes, transporters and other protein targets. We hope that the Concise Guide will provide for researchers, teachers and students a state‐of‐the art source of accurate, curated information on the background to their work that they will use in the Introductions to their Research Papers or Reviews, or in supporting their teaching and studies. We recommend that any citations to information in the Concise Guide are presented in the following format: Alexander SPH et al. (2019). The Concise Guide to PHARMACOLOGY 2019/20: Introduction and Other Protein Targets. Br J Pharmacol 176: S1–S20. In this overview are listed protein targets of pharmacological interest, which are not G protein‐coupled receptors, ion channels, nuclear hormone receptors, catalytic receptors, transporters or enzymes.

Overview

Adiponectin receptors (provisional nomenclature, http://www.ensembl.org/Homo_sapiens/Gene/Family/Genes?family=ENSFM00500000270960) respond to the 30 kDa complement‐related protein hormone adiponectin (also known as https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:13633: adipocyte, C1q and collagen domain‐containing protein; ACRP30, adipose most abundant gene transcript 1; apM‐1; gelatin‐binding protein: http://www.uniprot.org/uniprot/Q15848) originally cloned from adipocytes [http://www.ncbi.nlm.nih.gov/pubmed/8619847?dopt=AbstractPlus]. Although sequence data suggest 7TM domains, immunological evidence indicates that, contrary to typical 7TM topology, the carboxyl terminus is extracellular, while the amino terminus is intracellular [http://www.ncbi.nlm.nih.gov/pubmed/12802337?dopt=AbstractPlus]. Signalling through these receptors appears to avoid G proteins; modelling based on the crystal structures of the adiponectin receptors suggested ceramidase acivity, which would make these the first in a new family of catalytic receptors [http://www.ncbi.nlm.nih.gov/pubmed/25855295?dopt=AbstractPlus].

Comments

T‐Cadherin (https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:1753, http://www.uniprot.org/uniprot/P55290) has also been suggested to be a receptor for (hexameric) adiponectin [http://www.ncbi.nlm.nih.gov/pubmed/15210937?dopt=AbstractPlus].

Overview

Coagulation as a process is interpreted as a mechanism for reducing excessive blood loss through the generation of a gel‐like clot local to the site of injury. The process involves the activation, adhesion (see http://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=760), degranulation and aggregation of platelets, as well as proteins circulating in the plasma. The coagulation cascade involves multiple proteins being converted to more active forms from less active precursors, typically through proteolysis (see http://www.guidetopharmacology.org/GRAC/FamilyDisplayForward?familyId=759&familyType=ENZYME). Listed here are the components of the coagulation cascade targetted by agents in current clinical usage.

Overview

Transthyretin (TTR) is a homo‐tetrameric protein which transports thyroxine in the plasma and cerebrospinal fluid and retinol (vitamin A) in the plasma. Many disease causing mutations in the protein have been reported, many of which cause complex dissociation and protein mis‐assembly and deposition of toxic aggregates amyloid fibril formation [http://www.ncbi.nlm.nih.gov/pubmed/23716704?dopt=AbstractPlus]. These amyloidogenic mutants are linked to the development of pathological amyloidoses, including familial amyloid polyneuropathy (FAP) [http://www.ncbi.nlm.nih.gov/pubmed/12978172?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/8894411?dopt=AbstractPlus], familial amyloid cardiomyopathy (FAC) [http://www.ncbi.nlm.nih.gov/pubmed/9017939?dopt=AbstractPlus], amyloidotic vitreous opacities, carpal tunnel syndrome [http://www.ncbi.nlm.nih.gov/pubmed/10403814?dopt=AbstractPlus] and others. In old age, non‐mutated TTR can also form pathological amyloid fibrils [http://www.ncbi.nlm.nih.gov/pubmed/7016817?dopt=AbstractPlus]. Pharmacological intervention to reduce or prevent TTR dissociation is being pursued as a theapeutic strategy. To date one small molecule kinetic stabilising molecule (http://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=8378) has been approved for FAP, and is being evaluated in clinical trials for other TTR amyloidoses.

Overview

Cluster of differentiation refers to an attempt to catalogue systematically a series of over 300 cell‐surface proteins associated with immunotyping. Many members of the group have identified functions as enzymes (for example, see http://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=1232) or receptors (for example, see http://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=2441). Many CDs are targeted for therapeutic gain using antibodies for the treatment of proliferative disorders. A full listing of all the Clusters of Differentiation proteins is not possible in the Guide to PHARMACOLOGY; listed herein are selected members of the family targeted for therapeutic gain.

Comments

The endogenous ligands for human PD‐1 are programmed cell death 1 ligand 1 (PD‐L1 aka http://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=7693 (https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:17635, http://www.uniprot.org/uniprot/Q9NZQ7)) and programmed cell death 1 ligand 2 (PD‐L2; https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:18731). These ligands are cell surface peptides, normally involved in immune system regulation. Expression of PD‐1 by cancer cells induces immune tolerance and evasion of immune system attack. Anti‐PD‐1 monoclonal antibodies are used to induce immune checkpoint blockade as a therapeutic intervention in cancer, effectively re‐establishing immune vigilance. http://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=7499 was the first anti‐PD‐1 antibody to be approved by the US FDA.

Overview

Fatty acid‐binding proteins are low molecular weight (100‐130 aa) chaperones for long chain fatty acids, fatty acyl CoA esters, eicosanoids, retinols, retinoic acids and related metabolites and are usually regarded as being responsible for allowing the otherwise hydrophobic ligands to be mobile in aqueous media. These binding proteins may perform functions extracellularly (e.g. in plasma) or transport these agents; to the nucleus to interact with nuclear receptors (principally PPARs and retinoic acid receptors http://www.ncbi.nlm.nih.gov/pubmed/17882463?dopt=AbstractPlus]) or for interaction with metabolic enzymes. Although sequence homology is limited, crystallographic studies suggest conserved 3D structures across the group of binding proteins.

Overview

The canonical Notch signalling pathway has four type I transmembrane Notch receptors (Notch1‐4) and five ligands (DLL1, 2 and 3, and Jagged 1‐2). Each member of this highly conserved receptor family plays a unique role in cell‐fate determination during embryogenesis, differentiation, tissue patterning, proliferation and cell death [http://www.ncbi.nlm.nih.gov/pubmed/20971825?dopt=AbstractPlus]. As the Notch ligands are also membrane bound, cells have to be in close proximity for receptorligand interactions to occur. Cleavage of the intracellular domain (ICD) of activated Notch receptors by γ‐secretase is required for downstream signalling and Notch‐induced transcriptional modulation [http://www.ncbi.nlm.nih.gov/pubmed/10206645?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/16530044?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/9620803?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/16530045?dopt=AbstractPlus]. This is why γ‐secretase inhibitors can be used to downregulate Notch signalling and explains their anticancer action. One such small molecule is http://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=7338 [http://www.ncbi.nlm.nih.gov/pubmed/19773430?dopt=AbstractPlus], although development of this compound has been terminated following an unsuccessful Phase II single agent clinical trial in metastatic colorectal cancer [http://www.ncbi.nlm.nih.gov/pubmed/22445247?dopt=AbstractPlus].

Aberrant Notch signalling is implicated in a number of human cancers [http://www.ncbi.nlm.nih.gov/pubmed/17344417?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/24651013?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/18079963?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/17173050?dopt=AbstractPlus], with http://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=8451 and http://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=8453 identified as antibody inhibitors of ligand:receptor binding [http://www.ncbi.nlm.nih.gov/pubmed/25388163?dopt=AbstractPlus].

Overview

Regulators of G protein signalling (RGS) proteins display a common RGS domain that interacts with the GTP‐bound Gα subunits of heterotrimeric G proteins, enhancing GTP hydrolysis by stabilising the transition state [http://www.ncbi.nlm.nih.gov/pubmed/8756726?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/9108480?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/9417641?dopt=AbstractPlus], leading to a termination of GPCR signalling. Interactions through protein: protein interactions of many RGS proteins have been identified for targets other than heteromeric G proteins. Sequence analysis of the 20 RGS proteins suggests four families of RGS: RZ, R4, R7 and R12 families. Many of these proteins have been identified to have effects other than through targetting G proteins. Included here is RGS4 for which a number of pharmacological inhibitors have been described.

The RZ family of RGS proteins is less well characterized than the other families [http://www.ncbi.nlm.nih.gov/pubmed/16765607?dopt=AbstractPlus]. It consists of RGS17 (also known as RGSZ2), RGS19 (also known as GAIP) and RGS20 (with several splice variants including RGSZ1 and Ret‐RGS). All members contain an N‐terminal cysteine string motif [http://www.ncbi.nlm.nih.gov/pubmed/17183362?dopt=AbstractPlus] which is a site of palmitoylation and could serve functions in membrane targeting, protein stability or aid protein‐protein interactions [http://www.ncbi.nlm.nih.gov/pubmed/17126529?dopt=AbstractPlus]. However, the function in the case of RZ family RGS proteins is not yet fully understood. Members of the RZ family of RGS proteins are the only RGS proteins that have selective GTPase activating‐protein (GAP) activity for Gαz, a function that resulted in the name of the family [http://www.ncbi.nlm.nih.gov/pubmed/9748279?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/15096504?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/9748280?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/1347957?dopt=AbstractPlus]. However, the members of the RZ family are able to also GAP Gαi/o members with varying selectivity.

This is the largest family of RGS proteins.

This family of RGS proteins shows some selectivity for Gai/o proteins.

The R12 family consists of RGS10, 12 and 14. RGS12 and 14 are large proteins with additional domains that can participate in protein‐protein interactions and other functions. In contrast, RGS10 is a small protein consisting of the RGS domain and small N‐ and C‐termini, similar to members of the R4 family. However, sequence homology of the RGS10 RGS domain clearly places it in the R12 family [http://www.ncbi.nlm.nih.gov/pubmed/26123306?dopt=AbstractPlus]. The Gαi/o‐Loco (GoLoco) motif in RGS12 and 14 has GDI activity (for Guanine nucleotide Dissociation Inhibitor) towards Gαi1, Gαi2 and Gαi3 [http://www.ncbi.nlm.nih.gov/pubmed/11387333?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/15951850?dopt=AbstractPlus]. Through this activity RGS12 and RGS14 can inhibit G protein signaling both by accelerating GTP hydrolysis and by preventing G protein activation. Splice variants of RGS12 and RGS14 also contain membrane targeting and protein‐protein interaction domains [http://www.ncbi.nlm.nih.gov/pubmed/11130074?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/11771424?dopt=AbstractPlus, http://www.ncbi.nlm.nih.gov/pubmed/9651375?dopt=AbstractPlus].

Overview

Although termed ’receptors’, the evidence for coupling through conventional signalling pathways is lacking. Initially described as a subtype of opioid receptors, there is only a modest pharmacological overlap and no structural convergence with the G protein‐coupled receptors; the crystal structure of the sigma1 receptor [http://www.ncbi.nlm.nih.gov/pubmed/27042935?dopt=AbstractPlus] suggests a trimeric structure of a single short transmembrane domain traversing the endoplasmic reticulum membrane, with the bulk of the protein facing the cytosol. A wide range of compounds, ranging from psychoactive agents to antihistamines, have been observed to bind to these sites.

Comments

http://www.guidetopharmacology.org/GRAC/LigandDisplayForward?ligandId=1606 also shows activity at opioid receptors. The sigma2 receptor has recently been reported to be http://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=2553 [http://www.ncbi.nlm.nih.gov/pubmed/28559337?dopt=AbstractPlus], a 4TM protein partner of NPC1, the Niemann‐Pick C1 protein, a 13TM cholesterol‐binding protein.

Overview

Tubulins are a family of intracellular proteins most commonly associated with microtubules, part of the cytoskeleton. They are exploited for therapeutic gain in cancer chemotherapy as targets for agents derived from a variety of natural products: taxanes, colchicine and vinca alkaloids. These are thought to act primarily through β‐tubulin, thereby interfering with the normal processes of tubulin polymer formation and disassembly.
