Predicted to enable 3'-5' RNA helicase activity. Predicted to be involved in nuclear-transcribed mRNA catabolic process, 3'-5' exonucleolytic nonsense-mediated decay and rescue of stalled ribosome. 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); PARTICIPATES IN RNA degradation pathway; INTERACTS WITH 2,6-dinitrotoluene; bisphenol A; cadmium dichloride.
