Abstract

Ypt/Rab proteins of the Has superfamily are regulators of protein transport in exo- and endocytosis. Like pas and Rho proteins, they have a slow intrinsic GTPase activity that can be accelerated by several orders of magnitude by GTPase-activating proteins (GAP). Here we describe a new member of a family of Ypt/Rab-specific GAPs, Msb4p/Gyp4p, that shares with other Gyp family members significant homology in the catalytic domain, recently identified in Gyp1p and Gyp7p. Purified Msb4p/Gyp4p acts primarily on Sec4p, Ypt6p and Ypt7p and might have a role in polarized secretion.
