This domain is found in members of the Dicer protein family which function in RNA interference, an evolutionarily conserved mechanism for gene silencing using double-stranded RNA (dsRNA) molecules. It is essential for the activity of Dicer [1,2]. It is a divergent double stranded RNA-binding domain [3]. The N-terminal alpha helix of this domain is in a different orientation to that found in canonical dsRNA-binding domains. This results in a change of charge distribution at the potential dsRNA-binding surface and in the N- and C-termini of the domain being in close proximity [4]. This domain has weak dsRNA-binding activity. It mediates heterodimerisation of Dicer proteins with their respective protein partners [4].	Domain
