Research Backgrounds

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.

Subcellular Location:

Nucleus.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
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.

Subunit Structure:

Monomer.

Family&Domains:

The FHA domain binds threonine-phosphorylated peptides from XRCC1/4, and is responsible for the recruitment of PNKP to the sites of DNA repair. The affinity is ten times greater if peptides are also phosphorylated on the serine preceeding the phosphothreonine.

In the N-terminal section; belongs to the DNA 3' phosphatase family.
