CRISPR-Cas12a target binding unleashes indiscriminate single-stranded DNase activity
Janice S. Chen,Enbo Ma,Lucas B. Harrington,Maria Da Costa,Xinran Tian,Joel M. Palefsky,Jennifer A. Doudna +6 more
TL;DR: It is shown that RNA-guided DNA binding unleashes indiscriminate single-stranded DNA cleavage activity by Cas12a that completely degrades ssDNA molecules, which is also a property of other type V CRISPR-Cas12 enzymes.

A Cas9-guide RNA complex preorganized for target DNA recognition
TL;DR: The guide RNA in the CRISPR-Cas immune/editing system is poised to initiate recognition of target DNA and is construe this as convergent evolution of a “seed” mechanism reminiscent of that used by Argonaute proteins during RNA interference in eukaryotes.

Obligate ligation-gated recombination (ObLiGaRe): custom-designed nuclease-mediated targeted integration through nonhomologous end joining.
TL;DR: ObLiGaRe is described, a new method for site-specific gene insertions that uses the efficient NHEJ pathway and acts independently of HR, and has enabled us to insert a 15-kb inducible gene expression cassette at a defined locus in human cell lines.
