Human DNA polymerase kappa extending opposite a cis-syn thymine dimer

Structural highlights

3pzp is a 6 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Ligands:	DTP, MG, TTD
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

POLK_HUMAN DNA polymerase specifically involved in DNA repair. Plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls. Depending on the context, it inserts the correct base, but causes frequent base transitions, transversions and frameshifts. Lacks 3'-5' proofreading exonuclease activity. Forms a Schiff base with 5'-deoxyribose phosphate at abasic sites, but does not have lyase activity.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7]
