Function

UREND_METTH Involved in DNA uracil repair (PubMed:17012282, PubMed:19240141, PubMed:20129830). Recognizes DNA uracil residues within double-stranded DNA and initiates DNA-U repair by endonucleotic incision on the 5'-side of the 2'-d-uridine residue, irrespective of the nature of the opposing nucleotide (PubMed:17012282, PubMed:19240141, PubMed:20129830). In addition, acts as an apurinic/apyrimidinic (AP) endonuclease hydrolyzing the DNA phosphodiester backbone immediately at the 5'-side of AP sites, and as a 3'-5' exonuclease (PubMed:15725624, PubMed:17012282). Strongly binds to double-stranded DNA (PubMed:15725624).^{[1] [2] [3] [4]}
