Additional Information
Gene ID 5591
Application & Usage Western blot analysis (0.5-4 µg/ml). However, the optimal conditions should be determined individually. The immunoaffinity-purified antibody detects a >350,000 kDa and a 180,000 kDa protein (believed to be a processed form of the catalytic subunit), corresponding to the expected molecular weight of DNA-PKcs, in samples from human, mouse, rat and hamster origins.

Protein Information
Synonyms HYRC, HYRC1
Function Serine/threonine-protein kinase that acts as a molecular sensor for DNA damage. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break (DSB) repair and V(D)J recombination. Must be bound to DNA to express its catalytic properties. Promotes processing of hairpin DNA structures in V(D)J recombination by activation of the hairpin endonuclease artemis (DCLRE1C). The assembly of the DNA-PK complex at DNA ends is also required for the NHEJ ligation step. Required to protect and align broken ends of DNA. May also act as a scaffold protein to aid the localization of DNA repair proteins to the site of damage. Found at the ends of chromosomes, suggesting a further role in the maintenance of telomeric stability and the prevention of chromosomal end fusion. Also involved in modulation of transcription. Recognizes the substrate consensus sequence [ST]-Q. Phosphorylates 'Ser-139' of histone variant H2AX/H2AFX, thereby regulating DNA damage response mechanism. Phosphorylates DCLRE1C, c-Abl/ABL1, histone H1, HSPCA, c-jun/JUN, p53/TP53, PARP1, POU2F1, DHX9, SRF, XRCC1, XRCC1, XRCC4, XRCC5, XRCC6, WRN, MYC and RFA2. Can phosphorylate C1D not only in the presence of linear DNA but also in the presence of supercoiled DNA. Ability to phosphorylate p53/TP53 in the presence of supercoiled DNA is dependent on C1D. Contributes to the determination of the circadian period length by antagonizing phosphorylation of CRY1 'Ser-588' and increasing CRY1 protein stability, most likely through an indirect machanism. Interacts with CRY1 and CRY2; negatively regulates CRY1 phosphorylation.

DNA-dependent protein kinase (DNA-PK) is made up of 3 subunits, 2 Ku proteins and a large catalytic subunit (DNA-PKcs). DNA-PKcs falls into the phosphatidyl-inositol 3-kinase superfamily altho µgh it does have serine/threonine protein kinase activity. This subunit migrates on SDS-PAGE gels as an intact and smaller processed form. In vitro, DNA-PK phosphorylates several transcription factors and other DNA-binding proteins and is believed to play a role in DNA damage recognition, repair and transcription. There is evidence to s µggest that DNA-PKcs may be a critical target for proteolysis by a caspase in apoptosis.
