Multiple nucleic acid cleavage modes in divergent type III CRISPR systems [PDF]

, 2016
CRISPR-Cas is an RNA-guided adaptive immune system that protects bacteria and archaea from invading nucleic acids. Type III systems (Cmr, Csm) have been shown to cleave RNA targets in vitro and some are capable of transcription-dependent DNA targeting ...

Rapid generation of endogenously driven transcriptional reporters in cells through CRISPR/Cas9 [PDF]

, 2015
CRISPR/Cas9 technologies have been employed for genome editing to achieve gene knockouts and knock-ins in somatic cells. Similarly, certain endogenous genes have been tagged with fluorescent proteins. Often, the detection of tagged proteins requires high

Unification of Cas protein families and a simple scenario for the origin and evolution of CRISPR-Cas systems

Biology Direct, 2011
Background The CRISPR-Cas adaptive immunity systems that are present in most Archaea and many Bacteria function by incorporating fragments of alien genomes into specific genomic loci, transcribing the inserts and using the transcripts as guide RNAs to ...
