| Tissue Specificity | Expressed in many tissues with highest expression in spleen and testis, and lowest expression in small intestine. Expressed in higher amount in pancreas, heart and kidney and at lower levels in brain, lung and liver. |
| Function | Plays a key role in the repair of DNA damage, functioning as part of both the non-homologous end-joining (NHEJ) and base excision repair (BER) pathways. Through its two catalytic activities, PNK ensures that DNA termini are compatible with extension and ligation by either removing 3'-phosphates from, or by phosphorylating 5'-hydroxyl groups on, the ribose sugar of the DNA backbone. |
