CC   -!- FUNCTION: Probably not a functional protein. Cells lacking A2 show no
CC       obvious alterations in mating, sporulation and cell growth (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00108}.
CC   -!- MISCELLANEOUS: S.cerevisiae mating-type protein A2 is identical to
CC       residues 92-210 of ALPHA2 and should not be confused with the mating-
CC       type protein A2 of other yeast species.
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 TALE/M-ATYP homeobox family. {ECO:0000305}.
CC   -!- CAUTION: There is no sequence for the expressed copy of a2 in strain
CC       S288c, because this strain is of mating type alpha. A sequence for the
CC       expressed copy of a2 can be found in other strains (AC P0CY12).
CC       {ECO:0000305}.
