Predicted to enable telomerase RNA binding activity and telomeric DNA binding activity. Involved in embryonic genitalia morphogenesis; nuclear-transcribed mRNA catabolic process, nonsense-mediated decay; and regulatory ncRNA-mediated post-transcriptional gene silencing. Predicted to be located in cytoplasm and nucleus. Predicted to be part of telomerase holoenzyme complex. Is an ortholog of human SMG6 (SMG6 nonsense mediated mRNA decay factor).
