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)
PREY

LRG1

L000000953, YDL240W
GTPase-activating protein (GAP); contains Rho1p-specific GAP activity, interacting with activated forms of Rho1p; functions along with Sac7p as a negative regulator of the Pkc1p-mediated cell wall integrity signaling pathway; negative regulator of cell wall 1,3-beta-glucan biosynthesis; required for efficient cell fusion; contains a RhoGAP domain and three Lin-11-Isl1-Mec-3 (LIM) domains
Saccharomyces cerevisiae (S288c)

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Regulation of LRG1 expression by RNA-binding protein Puf5 in the budding yeast cell wall integrity pathway.

Viet NTM, Duy DL, Saito K, Irie K, Suda Y, Mizuno T, Irie K

The PUF RNA-binding protein Puf5 is involved in regulation of the cell wall integrity (CWI) pathway in yeast. Puf5 negatively regulates expression of LRG1 mRNA, encoding for a GTPase-activating protein for Rho1 small GTPase. Here, we further analyzed the effect of Puf5 on LRG1 expression, together with Ccr4 and Pop2 deadenylases, Dhh1 decapping activator, and other PUF proteins. We found that ... [more]
