== Function == | |||
[https://www.uniprot.org/uniprot/CAS2_ALKHC CAS2_ALKHC] CRISPR (clustered regularly interspaced short palindromic repeat), is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements and conjugative plasmids). CRISPR clusters contain sequences complementary to antecedent mobile elements and target invading nucleic acids. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA). Involved in the integration of spacer DNA into the CRISPR cassette (By similarity). Functions as a dsDNA-specific endonuclease, acting on circular and linear DNA; has no activity on ssRNA or ssDNA.<ref>PMID:22942283</ref> | |||
