CRISPR-controlled proteases

Abstract

With the discovery of CRISPR-controlled proteases, CRISPR-Cas has moved beyond mere nucleic acid targeting into the territory of targeted protein cleavage. Here, we review the understanding of Craspase, the best-studied member of the growing CRISPR RNA-guided protease family. We recollect the original bioinformatic prediction and early experimental characterizations; evaluate some of the mechanistic structural intricacies and emerging biotechnology; discuss open questions and unexplained mysteries; and indicate future directions for the rapidly moving field of the CRISPR proteases.

Keywords: CRISPR; Craspase; caspases; gRAMP; protease; type III.
