POLL, DNA polymerase lambda, Pol Lambda, DNA polymerase beta-2, Pol beta2, DNA polymerase kappa
This gene encodes a DNA polymerase. DNA polymerases catalyze DNA-template-directed extension of the 3-end of a DNA strand. This particular polymerase, which is a member of the X family of DNA polymerases, likely plays a role in non-homologous end joining and other DNA repair processes. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2010],catalytic activity:Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).,cofactor:Manganese.,function:Repair polymerase. Involved in base excision repair (BER) responsible for repair of lesions that give rise to abasic (AP) sites in DNA. Has both DNA polymerase and terminal transferase activities. Has a 5-deoxyribose-5-phosphate lyase (dRP lyase) activity.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,similarity:Belongs to the DNA polymerase type-X family.,similarity:Contains 1 BRCT domain.,subunit:Binds PCNA.,tissue specificity:Expressed in a number of tissues. Abundant in testis.,
