This domain is found in Endoribonuclease Dicer from chordates. This dsRNA endoribonuclease is involved in the cleavage of long RNA precursors into short dsRNAs and plays a role in gene silencing. Dicer shows two N-terminal helicase domains (Pfam:PF04851 and Pfam:PF00271), a dimerisation domain (Pfam:PF03368), a Platform domain, a PAZ domain (Pfam:PF02170), two RNase III a/b domains (Pfam:PF00636) and a dsRNA-binding domain in its C-terminal region. This entry represents the partner-binding domain, which folds into a four-helix bundle. It is is responsible for the interactions with the dsRNA-binding proteins that support the enzymatic activity of Dicer [1,2].
