Genome wide transcription profiling reveals a major role for the transcription factor Atf1 in regulation of cell division in Schizosaccharomyces pombe

The mechanism underlying stringently controlled sequence of events in the eukaryotic cell cycle involves periodic transcription of a number of genes encoding important regulators of cell cycle, growth, proliferation and apoptosis. Deregulated activities of transcription factors that contribute to this programmed gene expression, are associated with many diseases including cancer. A detailed mechanistic understanding of the transcriptional control associated with cell division is, therefore, important. We have reported earlier that the transcription factor Atf1 in Schizosaccharomyces pombe can regulate G2–M transition by directly controlling the expression of the mitotic cyclin Cdc13 (1).To gain a better understanding of the role of Atf1 in cell cycle, we performed a microarray based identification of cell cycle related targets of Atf1. The microarray data are available at NCBI's Gene Expression Omnibus (GEO) Series (accession number GSE71820). Here we report the annotation of the genes whose expression get altered by Atf1 overexpression and also provide details related to sample processing and statistical analysis of our microarray data.
