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.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00108}.
CC -!- DEVELOPMENTAL STAGE: Only present in alpha-cells (classes II and III).
CC {ECO:0000269|PubMed:14638801}.
CC -!- MISCELLANEOUS: There are three genetic loci for mating type genes in
CC C.glabrata. MTL1 seems to be the expression locus that determines the
CC mating type of the cell, whereas MTL2 (containing MTL2A1) and MTL3
CC (containing MTL3ALPHA1 and MTL3ALPHA2) appear to represent silenced
CC repositories of mating type information. Notably, MTL3ALPHA2 contains a
CC unique stretch coding for 22 amino acids at the C-terminus that is not
CC shared by MTL1ALPHA2.
CC -!- MISCELLANEOUS: Haploid C.glabrata strains can switch mating type,
CC however, neither mating nor diploid forms of C.glabrata have been
CC observed so far.
CC -!- SIMILARITY: Belongs to the TALE/M-ATYP homeobox family. {ECO:0000305}.
