WebJan 27, 2015 · This work has shown that mating type is determined by alleles of a single genetic locus that codes for regulatory proteins governing genes encoding mating pheromones, pheromone receptors and downstream effectors controlling cell type. Some yeast strains are capable of switching mating type, a process involving gene … WebThe mating type locus (MAT) determines the three yeast cell types, a, α, and a/α. It has been proposed that alleles of this locus, MATa and MATα, encode regulators that …
WebAug 19, 2005 · The Genes That Control Mating Type The genes that determine the mating type of haploid strains are especially important and are easy to study. In this case we don't need to worry about getting mutants because two alternative alleles of the MAT gene -- MAT a (or just a ) and MAT (or just ) -- determine the two opposite mating types … WebJun 28, 2011 · 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.
