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

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.

Different nuclease requirements for exosome-mediated degradation of normal and nonstop mRNAs.

Schaeffer D, van Hoof A

Two general pathways of mRNA decay have been characterized in yeast. In one pathway, the mRNA is degraded by the cytoplasmic form of the exosome. The exosome has both 3' to 5' exoribonuclease and endoribonuclease activity, and the available evidence suggests that the exonuclease activity is required for the degradation of mRNAs. We confirm here that this is true for ... [more]
