PNKP

polynucleotide kinase 3'-phosphatase

On chromosome: 19q13.3-q13.4
Known also as: PNK;


NCBI Gene ID: 11284
NCBI Ensembl Id: ENSG00000039650
MIM Id: (from NCBI OMIM database) 605610
Species: Homo sapiens

The PNKP gene encodes a polynucleotide kinase 3-prime phosphatase, which catalyzes the 5-prime phosphorylation of nucleic acids and also has an associated 3-prime phosphatase activity, predictive of an important function in DNA repair following ionizing radiation or oxidative damage (Jilani et al., 1999 [PubMed 10446192]).[supplied by OMIM]
