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