Vps9p is a guanine nucleotide exchange factor involved in vesicle-mediated vacuolar protein transport.

The Journal of biological chemistry - 21 May 1999

Hama H, Tall G G, Horazdovsky B F

Abstract excerpt

Vacuolar protein sorting (vps) mutants of Saccharomyces cerevisiae missort and secrete vacuolar hydrolases. The gene affected in one of these mutants, VPS21, encodes a member of the Sec4/Ypt/Rab family of small GTPases. Rab proteins play an essential role in vesicle-mediated protein transport. Using both yeast two-hybrid assays and chemical cross-linking, we have identified another VPS gene product, Vps9p, that...
