Is predicted to encode a protein with the following domains: P-loop containing nucleoside triphosphate hydrolase; Dicer dimerisation domain; Helicase, C-terminal; Helicase conserved C-terminal domain; and Dicer dimerisation domain superfamily. Is an ortholog of C. elegans dcr-1. In C. elegans, dcr-1 is involved in several processes, including nucleobase-containing compound catabolic process; olfactory learning; and regulatory ncRNA-mediated gene silencing.
