Product Detail background:
Mammalian PNK catalyzes the phosphorylation of DNA at 5'-hydroxyl termini and can dephosphorylate its 3'-phosphate termini. It plays an important function in DNA repair following ionizing radiation or oxidative damage. PNK has been reported to participate in the repair of DNA-double strand breaks via PARP-1-dependent nonhomologous end-joining.

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 catalyticactivities, PNK ensures that DNA termini are compatible withextension and ligation by either removing 3'-phosphates from, or byphosphorylating 5'-hydroxyl groups on, the ribose sugar of the DNAbackbone.

Subunit:
Monomer (By similarity).

Subcellular Location:
Nucleus.

Tissue Specificity:
Expressed in many tissues with highestexpression in spleen and testis, and lowest expression in smallintestine (PubMed:10446192). Expressed in higher amount inpancreas, heart and kidney and at lower levels in brain, lung andliver (PubMed:10446193).

Post-translational modifications:
Phosphorylated upon DNA damage, probably by ATM or ATR.

DISEASE:
Defects in PNKP are the cause of epilepticencephalopathy, early infantile, type 10 (EIEE10) [MIM:613402]. Adisease characterized by microcephaly, infantile-onset seizures,severe intellectual disability and delayed motor milestones withabsent speech or only achieving a few words. Most patients alsohave behavioral problems with hyperactivity. Microcephaly isprogressive and without neuronal migration or structuralabnormalities, consistent with primary microcephaly.

Similarity:
In the N-terminal section; belongs to the DNA 3'phosphatase family.
Contains 1 FHA domain.
