Superkiller complex protein 3 (or Ski3) is a protein which in humans is encoded by gene SKIC3 (previously TTC37).^[5]^[6] As its name suggests, this protein is a component of the superkiller complex.^[6]

Structure

The length of the polypeptide chain is 1,564 amino acids, and the molecular weight is 175,486 Da.^[6] SKIC3 contains six tetratricopeptide repeat domains, explaining its previous name "TTC37" (tetratricopeptide repeat domain 37).^[6]

Function

SKIC3 is a component of the Ski complex which is involved in exosome mediated RNA decay.^[7]

Subcellular distribution

It is localized in the cytoplasmatic space and the cell nucleus.^[5]

Clinical significance

Mutation in the SKIC3 gene are associated with tricho-hepato-enteric syndrome.^[8]^[9]
