Where this comes from

Abstract

Class 2 CRISPR-Cas systems are characterized by effector modules consisting of single, large, multidomain proteins that appear to have been derived from mobile genetic elements. Some Class 2 effector proteins, such as Cas9 and Cas12a (Cpf1), have been successfully repurposed for genome engineering.
