BCK1

LAS3, SAP3, SLK1, SSP31, mitogen-activated protein kinase kinase kinase BCK1, L000000162, YJL095W
MAPKKK acting in the protein kinase C signaling pathway; the kinase C signaling pathway controls cell integrity; upon activation by Pkc1p phosphorylates downstream kinases Mkk1p and Mkk2p; MAPKKK is an acronym for mitogen-activated protein (MAP) kinase kinase kinase

ROM2

Rho family guanine nucleotide exchange factor ROM2, L000003182, YLR371W
GDP/GTP exchange factor (GEF) for Rho1p and Rho2p; mutations are synthetically lethal with mutations in rom1, which also encodes a GEF; Rom2p localization to the bud surface is dependent on Ack1p; ROM2 has a paralog, ROM1, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

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.

Publication

The PH domain of the yeast GEF Rom2p serves an essential function in vivo.

Lorberg A, Jacoby JJ, Schmitz HP, Heinisch JJ

In a screen designed to identify new upstream components of the Pkc1p-MAP kinase signal transduction pathway that responds to cell wall damage in yeast, we identified a new mutant allele of the ROM2 gene, which encodes a GDP/GTP exchange factor that acts on Rho1p. This allele, originally termed ubk1 (upstream of Bck1p) encodes a truncated protein that lacks the putative ... [more]
