Identification of small molecule inhibitors of the human DNA repair enzyme polynucleotide kinase/phosphataseDownload
Human polynucleotide kinase/phosphatase (hPNKP) is a bifunctional DNA repair enzyme that phosphorylates DNA 5’-termini and dephosphorylates DNA 3’-termini. hPNKP has been shown to be involved in both single- and double-strand break repair, and cancer cells depleted of hPNKP show significant...
Synthetic lethal targeting of polynucleotide kinase/phosphatase and its potential role in directed cancer therapiesDownload
Synthetic lethality arises when simultaneous disruption of two non-essential, non-allelic genes in the same cell causes lethality. This phenomenon has been shown to occur between proteins involved in DNA repair and much attention to date has focused on poly(ADP-ribose) polymerase and the BRCA...
