Is predicted to encode a protein with the following domains: Double-stranded RNA binding motif; Alcohol dehydrogenase transcription factor Myb/SANT-like; Double-stranded RNA-binding domain; and MADF domain. Is an ortholog of C. elegans rde-4. In C. elegans, rde-4 is involved in regulatory ncRNA-mediated post-transcriptional gene silencing and siRNA processing.
