Target data
Function
Plays a key role in the repair of DNA damage, functioning as part of both the non-homologous end-joining (NHEJ) and base excision repair (BER) pathways (PubMed:10446192, PubMed:10446193, PubMed:15385968, PubMed:20852255, PubMed:28453785). Through its two catalytic activities, PNK ensures that DNA termini are compatible with extension and ligation by either removing 3'-phosphates from, or by phosphorylating 5'-hydroxyl groups on, the ribose sugar of the DNA backbone (PubMed:10446192, PubMed:10446193).

For more information, read more on recombinant antibodies.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
Supplementary info
- This supplementary information is collated from multiple sources and compiled automatically.
- Activity summary
The Polyribonucleotide 5'-hydroxyl-kinase 3'-phosphatase often known as PNK or PNKP protein is a dual-function enzyme necessary in DNA repair processes. PNKP with a mass of about 57 kDa performs both kinase and phosphatase activities. It removes 3'-phosphates and phosphorylates 5'-hydroxyl groups in polynucleotides preparing them for subsequent repair. This enzyme is expressed in various tissues with significant levels in the brain indicating its widespread importance in cellular processes.
- Biological function summary
PNKP protein is integral to maintaining genome stability by facilitating the repair of single-strand breaks and double-strand breaks in DNA. It is not part of a complex but often collaborates with other repair proteins through its enzymatic functions. PNKP ensures repaired DNA ends are properly processed to allow accurate ligation by DNA ligases contributing to the integrity of the genetic material in cells.
- Pathways
PNKP operates mainly in the DNA repair pathways specifically in Base Excision Repair (BER) and Non-Homologous End Joining (NHEJ). Within the BER pathway PNKP collaborates with proteins like DNA polymerase β and XRCC1 in processing damaged DNA. In the NHEJ pathway it associates with proteins like Ku and DNA-PKcs aligning for intricate repair of DNA double-strand breaks.
- Associated diseases and disorders
Mutations and malfunctions in PNKP are linked to neurological disorders and cancer. Dysfunctions in PNKP activity associate with neurodegenerative conditions like Microcephaly with Seizures due to its role in efficient DNA repair in neuronal tissues. Additionally its connection to DNA Repair pathways links PNKP malfunction with increased cancer risk. PNKP involvement with proteins like ATM and ATR signals its importance as these are key players in the cellular response to DNA damage particularly in preventing tumorigenesis.
