Predicted to enable RNA helicase activity. Predicted to be involved in nuclear-transcribed mRNA catabolic process, 3'-5' exonucleolytic nonsense-mediated decay. Predicted to act upstream of or within RNA catabolic process. Predicted to be part of Ski complex. Human ortholog(s) of this gene implicated in trichohepatoenteric syndrome 2. Orthologous to human SKIC2 (SKI2 subunit of superkiller complex).
