Protein

Superkiller protein 3

Gene

SKI3

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Component of the SKI complex involved in 3'-mRNA degradation pathway. Represses dsRNA virus propagation by specifically blocking translation of viral mRNAs, perhaps recognizing the absence of CAP or poly(A). Essential for cell growth only in the presence of M1 replicon.9 Publications

Miscellaneous

Present with 11900 molecules/cell in log phase SD medium.1 Publication

Interactioni

Subunit structurei

Component of the SKI complex composed of at least SKI2, SKI3 and SKI8. The SKI complex interacts with SKI7, which makes the link between the SKI complex and the exosome in order to perform mRNA degradation.2 Publications
