Key result
Four helically packed Cmr4 subunits form the backbone of the Cmr complex, acting as a platform to support crRNA binding and target RNA cleavage via a hook-like structural feature.

No immediate clinical implications; extends CRISPR-Cas structural models but leaves open therapeutic translation.
The study reveals the structural mechanism by which the Cmr4 subunit of the CRISPR-Cas Cmr complex facilitates crRNA binding and target RNA cleavage.
Ramia et al. (2014) studied this question. Mutagenesis and structural analysis of Cmr4 subunit was evaluated on crRNA binding and target RNA cleavage. Four helically packed Cmr4 subunits form the backbone of the Cmr complex, acting as a platform to support crRNA binding and target RNA cleavage via a hook-like structural feature.
