== Function ==
[https://www.uniprot.org/uniprot/CAS3_THET8 CAS3_THET8] 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). Cas3 plus Cascade participate in CRISPR interference, the third stage of CRISPR immunity. The N-terminal domain (residues 6-260) acts as a ssDNA endonuclease, has no activity on dsDNA.<ref>PMID:21775431</ref>
