title: Thirty-three years later, a glimpse at the ribonuclease III active site.
abstract: RNase III endonucleases cleave double-stranded RNA, transforming precursor RNAs into mature RNAs that act in pre-mRNA splicing, RNA modification, translation, gene silencing, and the regulation of developmental timing. The recently solved structure of an RNase III endonuclease domain provides a hint at how this family of ribonucleases functions.
