Overview:

CRISPR-Cas systems constitute the adaptive immune system in bacteria via RNA-guided endonucleases (1,2). This system has been leveraged to create an exemplary genome editing tool with applications in both basic research and therapeutics development (3). PsmCas13b is a CRISPR-Cas effector that belongs to the class 2 subtype VI-B (3). It processes its own CRISPR array with short and long direct repeats, cleaves target RNA, and exhibits collateral RNase activity (3). It has been shown to effectively target and silence distinct mammalian ssRNA viruses (4).
