Expanding the CRISPR Toolbox: Targeting RNA with Cas13b.
In this issue of Molecular Cell, Smargon et al. (2017) unearth Cas13b from type VI-B CRISPR-Cas immune systems and characterize its RNA-guided, RNA-targeting activity, including regulation by the novel co-factors Csx27 and Csx28, as well as non-specific collateral RNA damage.
