Is predicted to encode a protein with the following domains: Telomerase activating protein Est1; Est1 DNA/RNA binding domain; PIN-like domain superfamily; Tetratricopeptide-like helical domain superfamily; Telomerase activating protein Est1, N-terminal; PIN domain; and DNA/RNA-binding domain, Est1-type. Is an ortholog of C. elegans smg-6. In C. elegans, smg-6 is involved in embryonic genitalia morphogenesis; nuclear-transcribed mRNA catabolic process, nonsense-mediated decay; and regulatory ncRNA-mediated post-transcriptional gene silencing.
