MPT5

HTR1, PUF5, UTH4, L000001146, YGL178W
mRNA-binding protein of the PUF family; binds to the 3' UTR of specific mRNAs, including those involved in mating type switching, cell wall integrity, chronological lifespan, chromatin modification, and spindle pole body architecture; recruits the CCR4-NOT deadenylase complex to mRNAs along with Dhh1p and Dcp1p to promote deadenylation, decapping, and decay; also interacts with the Caf20p translational initiation repressor, affecting its mRNA target specificity
Saccharomyces cerevisiae (S288c)
PREY

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 Growth Defect

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

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]
