[[http://www.uniprot.org/uniprot/MTAL2_YEAST MTAL2_YEAST]] Mating type proteins are sequence specific DNA-binding proteins that act as master switches in yeast differentiation by controlling gene expression in a cell type-specific fashion. Transcriptional corepressor that binds cooperatively with MCM1 to a 31-basepair DNA sequence termed the a-specific gene (asg) operator, to repress the transcription of a-cell-specific genes. Additionally, in a/alpha diploid cells, binds cooperatively with the A1 protein to a 21-basepair DNA sequence termed the haploid-specific gene (hsg) operator, to repress transcription of haploid-specific genes and of MATALPHA1.<ref>PMID:8664541</ref> [[http://www.uniprot.org/uniprot/MCM1_YEAST MCM1_YEAST]] Transcription factor required for the efficient replication of minichromosomes and the transcriptional regulation of early cell cycle genes. Activates transcription of ECB-dependent genes during the G1/M phase. Genes that contain a ECB (early cell box) element in their transcription regulatory region are transcribed only during G1/M phases. Interacts with the alpha-2 repressor or with the alpha-1 activator thereby regulating the expression of mating-type-specific genes. With ARG80, ARG81 and ARG82, coordinates the expression of arginine anabolic and catabolic genes in response to arginine.
