Protein
CRISPR-associated endoribonuclease Cas2 1
Organism
Thermus thermophilus (strain HB27 / ATCC BAA-163 / DSM 7039)
Function
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). Functions as a ssRNA-specific endoribonuclease. Involved in the integration of spacer DNA into the CRISPR cassette (By similarity).
Similarity
Belongs to the CRISPR-associated endoribonuclease Cas2 protein family.
