Gene Information from Publications

Publication Link Summary of findings
17650498 XRCC1 enhances the capacity of hPNK to discriminate between strand breaks with 5'-OH termini and those with 5'-phosphate termini; and XRCC1 stimulates hPNK activity by displacing hPNK from the phosphorylated DNA product
17638872 polynucleotide kinase participates in repair of DNA double-strand breaks by nonhomologous end joining but not homologous recombination
12032095 Involvement of human polynucleotide kinase in double-strand break repair by non-homologous end joining
16364363 Data show that polynucleotide kinase is associated with the PARP-1-dependent end-joining pathway, and show functional parallels between the PARP-1 and DNA-PK-dependent end-joining processes.
14556639 First direct physical evidence for ternary complex formation involving a polynucleotide kinase, AMP-PNP, and an oligonucleotide, supports a reaction mechanism in which ATP and DNA bind simultaneously to the enzyme.
