Saccharomyces cerevisiae Mpt5p interacts with Sst2p and plays roles in pheromone sensitivity and recovery from pheromone arrest.

Molecular and cellular biology - 1 Jun 1997

Chen T, Kurjan J

Abstract excerpt

SST2 plays an important role in the sensitivity of yeast cells to pheromone and in recovery from pheromone-induced G1 arrest. Recently, a family of Sst2p homologs that act as GTPase-activating proteins (GAPs) for G alpha subunits has been identified. We have identified an interaction between Sst2p and the previously identified Mpt5p by using the two-hybrid system. Loss of Mpt5p function resulted in a...
