产品介绍：DNA PK is the key component of the non-homologous end-joining （NHEJ） pathway of DSB repair in mammalian cells. DNA PK consists of a heterodimeric DNA-binding subunit （Ku70/80） ａnd an approximately 465 kDa catalytic subunit （DNA PKcs）. DNA PKcs is a serine/threonine protein kinase whose activity is greatly stimulated by its recruitment to DNA breaks by the Ku heterodimer.Function : Serine/threonine-protein kinase that acts as a molecular sensor for DNA damage. Involved in DNA nonhomologous 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.Subunit : DNA-PK is a heterotrimer of PRKDC ａnd the Ku p70-p86 （XRCC6-XRCC5） dimer. Formation of this complex may be promoted by interaction with ILF3. Associates with the DNA-bound Ku heterodimer, but it can also bind to ａnd be activated by free DNA. Interacts with DNA-PKcs-interacting protein （KIP） with the region upstream the kinase domain. PRKDC alone also interacts with ａnd phosphorylates DCLRE1C, thereby activating the latent endonuclease activity of this protein. Interacts with C1D. Interacts with TTI1 ａnd TELO2.Subcellular Location : Nucleus.Post-translational modifications : Phosphorylated upon DNA damage, probably by ATM or ATR. Autophosphorylated on Thr-2609, Thr-2638 ａnd Thr-2647. Thr-2609 is a DNA damage-inducible phosphorylation site （inducible with ionizing radiation, IR）. Autophosphorylation induces a conformational change that leads to remodeling of the DNA-PK complex, requisite for efficient end processing ａnd DNA repair.S-nitrosylated by GAPDH.Similarity : Belongs to the PI3/PI4-kinase family.Contains 1 FAT domain. Contains 1 FATC domain. Contains 2 HEAT repeats. Contains 1 PI3K/PI4K domain. Contains 3 TPR repeats.DNA依赖性蛋白激酶（DNA PKcs） 是哺乳动物细胞DNA损伤修复的关键酶,是哺乳类细胞蛋白质丝/苏氨酸激酶，位于细胞核.
