Aliases GYP3
Feature type ORF, Verified
Coordinates Chr XIV:80640..82541
Primary SGDID S000005237


Description of YNL293W: Rab GTPase-activating protein; regulates endocytosis via activation of Vps21p and Ypt7p; also acts on Ypt52p and Sec4p; also required for proper actin organization; localizes to the plasma membrane and sites of polarized growth, and a portion localizes to endosomes and vacuoles; similar to Msb4p[1][2][3][4]
