DHH1

DExD/H-box ATP-dependent RNA helicase DHH1, L000000504, YDL160C
Cytoplasmic DExD/H-box helicase, stimulates mRNA decapping; coordinates distinct steps in mRNA function and decay, interacts with both the decapping and deadenylase complexes, role in translational repression, mRNA decay, and processing body dynamics; may have a role in mRNA export; C-terminus of Dhh1p interacts with Ngr1p and promotes POR1, but not EDC1 mRNA decay; forms cytoplasmic foci upon DNA replication stress
Saccharomyces cerevisiae (S288c)
PREY

STM1

MPT4, L000002574, YLR150W
Protein required for optimal translation under nutrient stress; perturbs association of Yef3p with ribosomes; involved in TOR signaling; binds G4 quadruplex and purine motif triplex nucleic acid; helps maintain telomere structure; protein abundance increases in response to DNA replication stress; serves as a ribosome preservation factor both during quiescence and recovery
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.

Stm1 modulates mRNA decay and Dhh1 function in Saccharomyces cerevisiae.

Balagopal V, Parker R

The control of mRNA degradation and translation are important for the regulation of gene expression. mRNA degradation is often initiated by deadenylation, which leads to decapping and 5'-3' decay. In the budding yeast Saccharomyces cerevisae, decapping is promoted by the Dhh1 and Pat1 proteins, which appear to both inhibit translation initiation and promote decapping. To understand the function of these ... [more]
