Activity of the enzyme seems to be attenuated by autophosphorylation.,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, c-myc\/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 TP53\/p53 in the presence of supercoiled DNA is dependent on C1D.,PTM: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.,similarity:Belongs to the PI3\/PI4-kinase family.,similarity:Contains 1 FAT domain.,similarity:Contains 1 FATC domain.,similarity:Contains 1 PI3K\/PI4K domain.,similarity:Contains 2 HEAT repeats.,similarity:Contains 3 TPR repeats.,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.,\u003c\/p\u003e\n\n\u003cp\u003eCondition: Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.\u003c\/p\u003e\n\n\u003cp\u003eStorage Instructions: -20°C\/1 year\u003c\/p\u003e\n\n\u003cp\u003eRecommended dilutions: WB 1:1000-2000 ELISA 1:5000-20000\u003c\/p\u003e\n\n\u003cp\u003eAlternative Names: DNA-dependent protein kinase catalytic subunit (DNA-PK catalytic subunit;DNA-PKcs;EC 2.7.11.1;DNPK1;p460)\u003c\/p\u003e \n\n\u003cp\u003eApplications: WB; ELISA\u003c\/p\u003e\n\n\u003cp\u003eSpecies Cross-Reactivity: Human; Mouse\u003c\/p\u003e\n\n\u003cp\u003eGeneID (Human): 5591\u003c\/p\u003e\n\n\u003cp\u003eProtein MW (KDa): 450\u003c\/p\u003e\n\n\u003cp\u003eSWISS: P78527\u003c\/p\u003e\n\n\u003cp\u003eSource: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"Reed Bio","offers":[{"title":"50μL","offer_id":45121244659891,"sku":"RA24267-50","price":336.0,"currency_code":"CAD","in_stock":true},{"title":"100μL","offer_id":45121244692659,"sku":"RA24267-100","price":448.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/logo_dfedaa14-49e8-4d37-b37a-d05cfed7e571.png?v=1773345654","url":"https:\/\/afsbio.com\/products\/dna-pk-phospho-thr2609-rabbit-polyclonal-antibody-ra24267","provider":"AFSBio Inc.","version":"1.0","type":"link"}
