Function

[DPOLL_HUMAN] 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.[1] [2]

Publication Abstract from PubMed

Pol lambda is a family X member believed to fill short gaps during DNA repair. Here we report crystal structures of Pol lambda representing three steps in filling a single-nucleotide gap. These structures indicate that, unlike other DNA polymerases, Pol lambda does not undergo large subdomain movements during catalysis, and they provide a clear characterization of the geometry and stereochemistry of the in-line nucleotidyl transfer reaction.

A closed conformation for the Pol lambda catalytic cycle.,Garcia-Diaz M, Bebenek K, Krahn JM, Kunkel TA, Pedersen LC Nat Struct Mol Biol. 2005 Jan;12(1):97-8. Epub 2004 Dec 19. PMID:15608652[3]
