This domain adopts a novel protein fold that is unique to the Cas9 family. It is positioned in the structure-DNA-complex to recognise the PAM sequence on the non-complementary DNA strand of the crRNA. PAM sequence is protospacer-adjacent motifs on DNA. See family CRISPR-DR2, Rfam:RF01315. Cas9 carries two nuclease domains, HNH and RuvC, which cleave the DNA strands that are complementary and non-complementary to the 20 nucleotide guide sequence in crRNAs, respectively [1].

This domain, and the HNH (Pfam:PF13395) domain of Cas9, are used to cleave the DNA strands complementary (target) and non-complementary (non-target) to the crRNA, respectively [5]. This domain is related to Pfam:PF18541.
