RNase III is a type of ribonuclease that specifically binds to and cleaves double-stranded RNA (dsRNA).[1] There are four subdivisions, known as Class 1, 2, 3, and 4.

Prokaryotic ribonuclease III (EC (gene rnc)[2] is an enzyme that digests double-stranded RNA. It is involved in the processing of ribosomal RNA precursors and of some mRNAs.
