VPS21

VPS12, VPT12, YPT21, YPT51, Rab family GTPase VPS21, L000002474, YOR089C
Endosomal Rab family GTPase; required for endocytic transport and sorting of vacuolar hydrolases; required for endosomal localization of the CORVET complex; required with YPT52 for MVB biogenesis and sorting; involved in autophagy and ionic stress tolerance; geranylgeranylation required for membrane association; protein abundance increases in response to DNA replication stress; mammalian Rab5 homolog; VPS21 has a paralog, YPT53, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

SAC6

ABP67, fimbrin, L000001793, YDR129C
Fimbrin, actin-bundling protein; cooperates with Scp1p (calponin/transgelin) in the organization and maintenance of the actin cytoskeleton; relocalizes from plasma membrane to cytoplasm upon DNA replication stress

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.

Use of a synthetic lethal screen to identify yeast mutants impaired in endocytosis, vacuolar protein sorting and the organization of the cytoskeleton.

Singer-Krueger B, Ferro-Novick S

To identify new genes whose products act on the endocytic and vacuolar protein sorting pathways, we screened for mutants that display synthetic growth defects with delta ypt51, a mutant impaired in membrane traffic at a point where these pathways intersect. Seven mutants that fell into six different complementation groups were found to fit this criterium. Two of the mutants (ysl1 ... [more]
