Cas9 (CRISPR associated protein 9, formerly called Cas5, Csn1, or Csx12) is a 160 kilodalton protein which plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids, and is heavily utilized in genetic engineering applications.
Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system. Gene editing with CRISPR-Cas9 involves a Cas9 nuclease and an engineered guide RNA, which come together to allow for the precise "cutting" of one or both strands of DNA at specific locations within the genome.

Cas9 uses cell-specific promoters allowing a controlled use of the Cas9. Cas9 is an accurate method of treating diseases due to the targeting of the Cas9 enzyme only affecting certain cell types. The cells undergoing the Cas9 therapy can also be removed and reintroduced to provide amplified effects of the therapy. [133]
But Cas9 will not cleave the protospacer sequence unless there is an adjacent PAM sequence. The spacer in the bacterial CRISPR loci will not contain a PAM sequence, and thus will not be cut by the nuclease, but the protospacer in the invading virus or plasmid will contain the PAM sequence, and thus will be cleaved by the Cas9 nuclease.

Over 130 years after his gruesome murders in East London, England, the descendants of his victims are looking to unmask the identity of the serial killer popularly known as Jack the Ripper. The ...
Others had a full shave. They were there to celebrate the gold and bronze medals for teammates Franjo von Allmen and Alexis Monney, respectively. Odermatt finished fifth in Sunday's race.
The first game in Unrivaled history featured Skylar Diggins-Smith making the decisive shot -- even though her team was already in the lead. That aspect is one of the many differences between the 3 ...
Targeted gene knockout using CRISPR/Cas9 requires the use of a delivery system to introduce the sgRNA and Cas9 into the cell. Although a number of different delivery systems are potentially available for CRISPR, [ 37 ] [ 38 ] genome-wide loss-of-function screens are predominantly carried out using third generation lentiviral vectors.
