Bifunctional polynucleotide phosphatase/kinase (PNK), also referred to as polynucleotide kinase-3′-phosphatase, is a member of the DNA 3′ phosphatase family. PNK is the protein expressed by the gene PNKP and contains a 3′-phosphatase domain with similarity to L-2-haloacid dehalogenases and a reported ATP binding site. PNK is a nuclear protein that is involved in DNA repair following damage caused by radiation or oxidation. The protein catalyzes the phosphorylation of DNA at the hydroxy termini but can also dephosphorylate its 3′-phosphate termini. The highest levels of expression of PNK occur in testis, pancreas, spleen, kidney and heart.
