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)
PREY

SKI7

YOR29-27, YOR076C
Coupling protein for the Ski complex and cytoplasmic exosome; involved in 3'-5' RNA degradation; eRF3-like domain targets nonstop mRNA for degradation; null mutants have superkiller phenotype; SKI7 has a paralog, HBS1, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

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.

The ski7 antiviral protein is an EF1-alpha homolog that blocks expression of non-Poly(A) mRNA in Saccharomyces cerevisiae.

Benard L, Carroll K, Valle RC, Masison DC, Wickner RB

We mapped and cloned SKI7, a gene that negatively controls the copy number of L-A and M double-stranded RNA viruses in Saccharomyces cerevisiae. We found that it encodes a nonessential 747-residue protein with similarities to two translation factors, Hbs1p and EF1-alpha. The ski7 mutant was hypersensitive to hygromycin B, a result also suggesting a role in translation. The SKI7 product ... [more]
