This domain is found at the C-terminal end of Protein Dicer from Schizosaccharomyces pombe (Dcr1) and similar fungal sequences. Dcr1 processes double-stranded RNA (dsRNA) precursors endonucleolytically. This domain adopts an extended dsRNA binding domain fold that embeds a zinc-binding motif [1].	Domain
