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). Has endonuclease activity on pre-crRNA and dsDNA, using different active sites. A single-RNA guided endonuclease that is also capable of guiding crRNA processing; correct processing of pre-crRNA requires only this protein and the CRISPR locus (PubMed:26422227, PubMed:27096362). pre-crRNA processing proceeds by an intramolecular nucleophilic attack on the scissile phosphate by the 2'-OH of the upstream ribonucleotide, the divalent cation (which is bound by the crRNA) is probably required for ordering the crRNA pseudoknot and/or increasing RNA binding (PubMed:28431230). RNA mutagenesis studies show pre-crRNA cleavage is highly sequence- and structure-specific (PubMed:27096362). Forms a complex with crRNA and complementary dsDNA, where the crRNA displaces the non-target DNA strand and directs endonucleolytic cleavage of both strands of the DNA (PubMed:26422227, PubMed:27096362, PubMed:28431230). Cleavage results in staggered 5-base 5' overhangs 14-18 and 21-23 bases downstream of the PAM (protospacer adjacent motif) on the non-target and target strands respectively (PubMed:26422227, PubMed:28431230, PubMed:28562584). Both target and non-target strand DNA are probably independently cleaved in the same active site (PubMed:28431230, PubMed:28562584). When this protein is expressed in E.coli it prevents plasmids homologous to the first CRISPR spacer from transforming, formally showing it is responsible for plasmid immunity (PubMed:26422227).4 Publications

<p>This subsection of the ‘Function’ section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states.

Ca2+1 Publication, Mg2+4 PublicationsNote: Cleavage of dsDNA requires Mg2+ (PubMed:26422227, PubMed:28562584). Another report shows DNA cleavage occurs equally well in the presence of Ca2+ or Mg2+ (PubMed:27096362). Processing of pre-crRNA requires a divalent cation, preferably Mg2+ which is bound by the crRNA (PubMed:26593719, PubMed:28431230).5 Publications

This class of CRISPR enzymes recognize a 5' T-rich protospacer adjacent motif (PAM, TTN for this specific enzyme), unlike Cas9 enzymes which recognize 3' G-rich PAMs, thus this enzyme increases the possibilites for genome editing (PubMed:26422227). The simplicity of the Cas12a-crRNA directed DNA endonuclease activity has been used to target and modify DNA sequences in rice and tobacco (PubMed:27905529).1 Publication2 Publications

Has bilobed structure, with the REC lobe (residues 25-591) connected to the NUC lobe (662-1300) by a discontinuous wedge domain (PubMed:28431230, PubMed:28562584). The REC lobe binds the (pre-)crRNA and the crRNA-target DNA heteroduplex (PubMed:28431230, PubMed:28562584). The heteroduplex as well as part of the DNA downstream of the heteroduplex is protected in the central cavity formed by the NUC and REC lobes, which also positions target and non-target DNA for cleavage after domain rearrangement (PubMed:28431230, PubMed:28562584). The LKL region (residues 662 to 679) inserts into target dsDNA initiating its disruption to allow crRNA hybridization, is also involved in determining the non-target strand cleavage site (PubMed:28562584). A 'septum' formed by resdiues 197-204 and 1061-1070 separates the 2 DNA strands, preventing their reannealing, this region also influences the non-target cleavage site (PubMed:28562584).2 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i601E903DE68C80DE

<p>This subsection of the ‘Entry information’ section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called ‘Primary (citable) accession number’.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: A0Q7Q2
<p>This subsection of the ‘Entry information’ section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification (‘Last modified’).
