CC -!- FUNCTION: Mating type proteins are sequence specific DNA-binding
CC proteins that act as master switches in yeast differentiation by
CC controlling gene expression in a cell type-specific fashion. Silenced
CC copy of A1 at HMR.
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- MISCELLANEOUS: There are three genetic loci for mating type genes in
CC S.cerevisiae. MAT is the expression locus that determines the mating
CC type of the cell, whereas HML (containing HMLALPHA1 and HMLALPHA2) and
CC HMR (containing HMRA1 and HMRA2) represent silenced repositories of
CC mating type information. The mating type is determined by the MAT
CC locus, which contains either a copy of HML or of HMR. Diploid cells are
CC usually heterozygous for the MAT locus.
CC -!- SIMILARITY: Belongs to the MATA1 family. {ECO:0000305}.
CC -!- CAUTION: There is no sequence for the expressed copy of A1 in strain
CC S288c, because this strain is of mating type alpha. A sequence for the
CC expressed copy of A1 can be found in other strains (AC P0CY10).
CC {ECO:0000305}.
