Here, we show that the GTPase-activating protein Gyp7 inactivates the yeast vacuole Rab Ypt7 in vivo. To efficiently terminate Ypt7 signaling, Gyp7 requires downstream assistance from an inhibitory casein kinase I, Yck3. Yck3 mediates phosphorylation of at least two Ypt7 signaling targets: a tether, the Vps-C/homotypic fusion and vacuole protein sorting (HOPS) subunit Vps41, and a SNARE, Vam3. Phosphorylation of both substrates is opposed by Ypt7-guanosine triphosphate (GTP). We further demonstrate that Ypt7 binds not one but two Vps-C/HOPS subunits: Vps39, a putative Ypt7 nucleotide exchange factor, and Vps41. Gyp7-stimulated GTP hydrolysis on Ypt7 therefore appears to trigger both passive termination of Ypt7 signaling and active kinase-mediated inhibition of Ypt7's downstream targets. We propose that signal propagation through the Ypt7 pathway is controlled by integrated feedback and feed-forward loops. In this model, Yck3 enforces a requirement for the activated Rab in docking and fusion."xsd:string |
