YPT6

Rab family GTPase YPT6, L000002896, L000002948, YLR262C
Rab family GTPase; Ras-like GTP binding protein involved in the secretory pathway, required for fusion of endosome-derived vesicles with the late Golgi, maturation of the vacuolar carboxypeptidase Y; resides temporarily at the Golgi, dissociates into cytosol upon arrival of the Rab GTPaseYpt32p, which also functions in the late Golgi; Golgi-localized form is bound to GTP, while cytosolic form is GDP-bound; homolog of the mammalian Rab6

SEC23

GTPase-activating protein SEC23, L000001846, S000028412, YPR181C
GTPase-activating protein, stimulates the GTPase activity of Sar1p; component of the Sec23p-Sec24p heterodimer of the COPII vesicle coat, involved in ER to Golgi transport; substrate of Ubp3/Bre5 complex; ubiquitylated by Ub-ligase Rsp5p; proteasome-mediated degradation of Sec23p is regulated by Cdc48p

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Biochemical and genetic evidence for the involvement of yeast Ypt6-GTPase in protein retrieval to different Golgi compartments.

Luo Z, Gallwitz D

Yeast Ypt6p, the homologue of the mammalian Rab6 GTPase, is not essential for cell viability. Based on previous studies with ypt6 deletion mutants, a regulatory role of the GTPase either in protein retrieval to the trans-Golgi network or in forward transport between the endoplasmic reticulum (ER) and early Golgi compartments was proposed. To assess better the primary role(s) of Ypt6p, ... [more]
