MRT2, L000002960, L000003045, S000029311, YOL149W
Subunit of the Dcp1p-Dcp2p decapping enzyme complex; decapping complex removes the 5' cap structure from mRNAs prior to their degradation; enhances the activity of catalytic subunit Dcp2p; regulated by DEAD box protein Dhh1p; forms cytoplasmic foci upon DNA replication stress

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

The 3' to 5' degradation of yeast mRNAs is a general mechanism for mRNA turnover that requires the SKI2 DEVH box protein and 3' to 5' exonucleases of the exosome complex.

Anderson JS, Parker RP

One major pathway of mRNA decay in yeast occurs by deadenylation-dependent decapping, which exposes the transcript to 5' to 3' exonucleolytic degradation. We show that a second general pathway of mRNA decay in yeast occurs by 3' to 5' degradation of the transcript. We also show that the SKI2, SKI3, SKI6/RRP41, SKI8 and RRP4 gene products are required for 3' ... [more]
