Overview
Pnk1 polynucleotide kinase 3'-phosphatase. May be involved in double-strand break repair by non-homologous end joining. Required for normal response to DNA damage by gamma-radiation or camptothecin in S. pombe. Note: This description may include information from UniProtKB.
Protein type: EC 3.1.3.32; DNA binding protein; EC 2.7.1.78; Kinase, other; Phosphatase (non-protein)
Cellular Component: nucleolus; nucleus
Molecular Function: protein binding; ATP-dependent polydeoxyribonucleotide 5'-hydroxyl-kinase activity; purine nucleotide binding; polynucleotide 3'-phosphatase activity; endonuclease activity; double-stranded DNA binding; damaged DNA binding; nucleotide kinase activity; ATP binding
Biological Process: response to radiation; dephosphorylation; nucleotide-excision repair, DNA damage removal; DNA damage response, detection of DNA damage; response to oxidative stress; DNA-dependent DNA replication; DNA repair; nucleotide phosphorylation
Reference #:  Q96T60 (UniProtKB)
