New Type III CRISPR variant and programmable RNA targeting tool: Oh, thank heaven for Cas7-11

Ozcan et al. (2021) and van Beljouw et al. (2021) characterize a novel Type III-E CRISPR-Cas subtype, composed of a single polypeptide with crRNA processing and sequence-specific RNA cleavage activities, that provides a new RNA knockdown tool for mammalian cells with fewer off-target effects than current technologies.
