DCP2

PSU1, decapping enzyme complex catalytic subunit DCP1, L000002866, YNL118C
Catalytic subunit of the Dcp1p-Dcp2p decapping enzyme complex; removes the 5' cap structure from mRNAs prior to their degradation; also enters the nucleus and positively regulates transcription initiation; nudix hydrolase family member; forms cytoplasmic foci upon DNA replication stress
Saccharomyces cerevisiae (S288c)
PREY

XRN1

DST2, KEM1, RAR5, SEP1, SKI1, chromatin-binding exonuclease XRN1, L000000891, L000001902, YGL173C
Evolutionarily-conserved 5'-3' exonuclease; component of cytoplasmic processing (P) bodies involved in mRNA decay; also enters the nucleus and positively regulates transcription initiation and elongation; plays a role in microtubule-mediated processes, filamentous growth, ribosomal RNA maturation, and telomere maintenance; activated by the scavenger decapping enzyme Dcs1p
Saccharomyces cerevisiae (S288c)

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.

Global analysis of mRNA decay intermediates in Saccharomyces cerevisiae.

Harigaya Y, Parker R

The general pathways of eukaryotic mRNA decay occur via deadenylation followed by 3' to 5' degradation or decapping, although some endonuclease sites have been identified in metazoan mRNAs. To determine the role of endonucleases in mRNA degradation in Saccharomyces cerevisiae, we mapped 5' monophosphate ends on mRNAs in wild-type and dcp2 xrn1 yeast cells, wherein mRNA endonuclease cleavage products are ...

Negative Genetic

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.
