This study reveals different Cas3 activation mechanisms and a dual role of ATP in target degradation and collateral cleavage in target degradation and collateral cleavage.
Abstract
Jiang et al. show that the type I-A CRISPR system of Saccharolobus islandicus recruits Cas3 only after target recognition. Their study reveals different Cas3 activation mechanisms and a dual role of ATP in target degradation and collateral cleavage.
A CRISPR/Cas9 toolkit was established for the rice leaffolder using entirely endogenous regulatory elements and provides a system for functional genomics in this pest.

CRISPR-Cas systems in prokaryotes serve as adaptive immune systems that neutralize phage infections through RNA-guided nucleases. Immunization is achieved during the adaptation stage through Cas1-Cas2 integrase-mediated insertion of short foreign DNA snippets, termed spacers, into a CRISPR array in the host genome. Thi...

We constructed a CRISPR/Cas12a autocatalytic system based on a miRNA-triggered overhang blocker (OB) cleavage-recombination framework, in which Cas12a sequentially removed steric hindrance to initiate cyclic autocatalysis, enabling exponential signal amplification for visual miRNA detection without target pre-amplifica...
