The PAM is required for a Cas nuclease to cut and is generally found 3-4 nucleotides their target sites while designing their genome engineering experiments.

The canonical PAM is the sequence 5'-NGG-3', where "N" is any nucleobase followed by two guanine ("G") nucleobases. Guide RNAs can transport Cas9 to any locus in the genome for gene editing, but no editing can occur at any site other than one at which Cas9 recognizes PAM. The most commonly used Cas9 nuclease, derived from S. pyogenes, recognizes a PAM sequence of NGG that is found directly downstream of the target sequence in the genomic DNA, on the non-target strand. A short DNA sequence, the protospacer-adjacent motif (PAM), is frequently used to mark proper target sites.

Prokaryotic CRISPR-Cas systems defend bacterial cells from phage and plasmid infection. Strecker et al. characterized a CRISPR-Cas system that functions beyond adaptive immunity (see the Perspective by Hou and Zhang). Type V-K CRISPR-Cas from cyanobacteria was associated with a Tn7-like transposon and a natural nuclease–deficient effector Cas12k. Cas12k directed the insertion of Tn7-like

PAM sequences. The canonical PAM is the sequence 5'-NGG-3', where "N" is any nucleobase followed by two guanine ("G") nucleobases. Guide RNAs can transport Cas9 to any locus in the genome for gene editing, but no editing can occur at any site other than one at which Cas9 recognizes PAM.

Cas proteins have evolved a multitude of PAM-interacting domains,whichenablesthemtocopewithviralanti-CRISPRmeasuresthatalterthesequenceoraccessibility of PAM elements. In this review, we summarize known PAM recognition strategies for all CRISPR-Cas types. Se hela listan på blog.addgene.org 2019-12-01 · At these three target sites, the ratio of 5′-NAG-3′ PAM and 5′-NGA-3′ PAM to the total cleavage of PAMs was 0.21–0.23 and 0.08–0.14, respectively, and other types of PAM for a small portion at three target sequences. However, there are subtle differences in the PAM preferences of the Cas protein with the three spacer sequences. Like the Cas9 variants and orthologs described above, Cas12a also expands the range of sites that can be targeted by CRISPR to AT-rich regions or AT-rich genomes that lack the NGG PAM sites favored by SpCas9.
