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)

PKC1

CLY15, CLY5, CLY7, HPO2, STT1, protein kinase C, L000001446, L000000362, S000029091, YBL105C
Protein serine/threonine kinase; essential for cell wall remodeling during growth; localized to sites of polarized growth and the mother-daughter bud neck; homolog of the alpha, beta, and gamma isoforms of mammalian protein kinase C (PKC)
Kinome Project (Sc)
Saccharomyces cerevisiae (S288c)

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Saccharomyces cerevisiae MPT5 and SSD1 function in parallel pathways to promote cell wall integrity.

Kaeberlein M, Guarente L

Yeast MPT5 (UTH4) is a limiting component for longevity. We show here that MPT5 also functions to promote cell wall integrity. Loss of Mpt5p results in phenotypes associated with a weakened cell wall, including sorbitol-remedial temperature sensitivity and sensitivities to calcofluor white and sodium dodecyl sulfate. Additionally, we find that mutation of MPT5, in the absence of SSD1-V, is lethal ... [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.
