The PAM, also known as the protospacer adjacent motif, is a short specific sequence following the target DNA sequence that is essential for cleavage by Cas nuclease. The PAM is about 2-6 nucleotides downstream of the DNA sequence targeted by the guide RNA and the Cas nuclease cuts 3-4 nucleotides upstream of it.

The PAM sequence is of particular concern when trying to edit a gene using homology directed repair, since HDR-mediated gene editing is most efficient when target sites are located in close proximity to the region to be edited. The PAM is a 3-nt (NGG) sequence located immediately downstream of the single-guide RNA (sgRNA) target site, which plays an essential role in binding and for Cas9-mediated DNA cleavage. The first nucleotide is the least conserved, with G in nearly 50% of binding sites, while the second position with G in >90% of the binding sites, 8, 30 suggesting that NRG is not the optimal PAM for the designing of CRISPR/Cas9 sequences. Therefore, the exact effect of NRG PAM sequence on DNA cleavage of Cas9 is largely unclear. 31 I generated few transgenic plants for crisper cas9 mediated mutation, When I analyzed sequence for editing/mutation by sequencing I found that crisper cas9 has digested DNA at downstream of PAM The necessity of the Cas protein to bind a PAM stems from their origins in prokaryotic adaptive immune systems, where the PAM allows the enzyme to distinguish between a genomic site harboring a stored “memory” of a previous phage infection and a target site in the DNA of an invading phage. The PAM is a 3-nt (NGG) sequence located immediately downstream of the single-guide RNA (sgRNA) target site, which plays an essential role in binding and for Cas9-mediated DNA cleavage. Cas9 from Streptococcus pyogenes (SpCas9), recognizing an NGG protospacer adjacent motif (PAM), is a widely used nuclease for genome editing in living cells.

Three main phases are involved in CRISPR–Cas immunity: adaptation, expression and interference. For best results, a PAM site should be as close to the location of the desired mutation as possible. In the worm C. elegans , edits have been reported up to 50 bp from the PAM site, however efficiency for inducing a desired mutation or edit is inversely correlated to the number of base pairs from a PAM site 17 . Cas9 endonuclease complexed with a crRNA and separate tracrRNA cleaves foreign DNA containing a 20-nucleotide crRNA complementary sequence adjacent to the PAM sequence. (Figure not drawn to scale.) Cas9 nuclease, S. pyogenes , complexed with an sgRNA Cleavage occurs three nucleotides upstream of the PAM sequence (shown in red).
