PNKP
-
Official Full Name
polynucleotide kinase 3-phosphatase -
Overview
This locus represents a gene involved in DNA repair. In response to ionizing radiation or oxidative damage, the protein encoded by this locus catalyzes 5 phosphorylation and 3 dephosphorylation of nucleic acids. Mutations at this locus have been associated with microcephaly, seizures, and developmental delay. -
