Mammalian PNK catalyzes the phosphorylation of DNA at 5'-hydroxyl termini and can dephosphorylate its 3'-phosphate termini. It plays an important function in DNA repair following ionizing radiation or oxidative damage.PNK has been reported to participate in the repair of DNA-double strand breaks via PARP-1-dependent nonhomologous end-joining.

Flame resistant faceseal, Versaflo™

Supplier: LGC Standards PROMOCHEM

Purity estimate obtained from a combination of traditional analytical techniques is 99,3 ± 0,6% mass fraction, (95% coverage interval). The purity estimate by traditional analytical techniques was obtained by subtraction from 100% of total impurities by GC-FID, and Karl Fischer analysis. Supporting evidence is provided by elemental microanalysis and 1H NMR analysis.

ATM is a 370 kDa nuclear phosphoprotein involved in the autosomal recessive disease Ataxia Telangiectasia (AT). ATM belongs to a novel family of proteins associated with cell cycle regulation, apoptosis, and response to DNA damage repair (DNA damage caused by such things as ionizing irradiation activates ATM kinase). The C terminal region has extensive homology to the catalytic domains of Phosphatidylinositol 3 kinases (PI3 kinases).

Fanconi Anemia (FANC) is a human autosomal-recessive cancer susceptibility disorder characterized by congenital defects, progressive bone marrow failure, and cellular hypersensitivity to mitomycin C (MMC). The FANC subunit D2 protein is vital for cellular resistance to DNA cross-linking and the arrest of DNA synthesis after ionizing radiation.DNA damage activates the monoubiquitination of FANC D2, targeting nuclear foci containing the BRCA 1 protein.

The DNA damage checkpoint is a signal transduction pathway that has the ability to delay entry into mitosis. When DNA is damaged, the Check point kinases (CHKs) are known to act downstream of ATM to elicit appropriate responses such as cell cycle arrest. Chk1, for instance, is activated by ATM phosphorylation of serines 123, 178, 278, and 292 of the S phase-promoting cdc25A phosphatase and accelerates IR (ionizing radiation)induced degradation of cdc25A.
