Protein

Mating-type P-specific polypeptide Pi

Gene

matPi

Organism
Schizosaccharomyces kambucha (Fission yeast)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

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. Required for meiosis, but plays no role in conjugation (By similarity).By similarity

Miscellaneous

There are three genetic loci for mating type genes in fission yeast, mat1, mat2-P and mat3-M. Cell type is determined by the alternate allele present in mat1, either P (plus) in a h+ or M (minus) in a h- cell. Mat2-P and mat3-M serve as donor of information that is transposed to mat1 during a switch of mating type (By similarity).By similarity
