Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Error-prone DNA polymerase specifically involved in DNA repair (PubMed:15026325, PubMed:16357261). Plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls (PubMed:15026325, PubMed:16357261). Favors Hoogsteen base-pairing in the active site. Inserts the correct base with high-fidelity opposite an adenosine template (By similarity). Exhibits low fidelity and efficiency opposite a thymidine template, where it will preferentially insert guanosine (By similarity). May play a role in hypermutation of immunogobulin genes (By similarity). Forms a Schiff base with 5'-deoxyribose phosphate at abasic sites, but may not have lyase activity (By similarity).By similarity2 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.
