1 Here I review our studies on the final stages of the yeast secretory pathway that have led us to propose that adjacent Rabs on a pathway are networked to one another through their regulators; specifically we have shown that the Rab, Ypt32, in its GTP-bound form recruits both Sec2, the GEF that activates the downstream Rab, Sec4, as well as Gyp1, the GAP that inactivates the upstream Rab, Ypt1. rabs guanine nucleotide exchange factor SEC2 Saccharomyces cerevisiae S288C
