BEM1

SRO1, phosphatidylinositol-3-phosphate-binding protein BEM1, L000000167, YBR200W
Protein containing SH3-domains; involved in establishing cell polarity and morphogenesis; functions as a scaffold protein for complexes that include Cdc24p, Ste5p, Ste20p, and Rsr1p
Saccharomyces cerevisiae (S288c)

VPS1

GRD1, LAM1, SPO15, VPL1, VPT26, dynamin-like GTPase VPS1, L000002006, YKR001C
Dynamin-like GTPase required for vacuolar sorting; also involved in actin cytoskeleton organization, endocytosis, late Golgi-retention of some proteins, regulation of peroxisome biogenesis
Saccharomyces cerevisiae (S288c)

Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.

Bem1p is a positive regulator of the homotypic fusion of yeast vacuoles.

Xu H, Wickner W

Docked vacuoles are believed to undergo rapid lipid mixing during hemifusion and then a slow, rate-limiting completion of fusion and mixing of lumenal contents. Previous genomic analysis has suggested that Bem1p, a scaffold protein critical for cell polarity, may support vacuole fusion. We now report that bem1Delta strains have fragmented vacuoles (vps class B and C). During in vitro fusion ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
