CRISPR-associated nuclease/helicase Cas3 subtype I-F/YPEST

UniProtKB accession:  Q02ML8

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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 (Potential).
