DNA-PK is a heterotrimer of PRKDC and the Ku dimer (composed of XRCC6/Ku70 and XRCC5/Ku86) (PubMed:15758953, 25670504). Formation of this complex may be promoted by interaction with ILF3 (PubMed:9442054). Component of the core long-range non-homologous end joining (NHEJ) complex (also named DNA-PK complex) composed of PRKDC, LIG4, XRCC4, XRCC6/Ku70, XRCC5/Ku86 and NHEJ1/XLF (PubMed:15758953, 25670504, 33854234). Additional component of the NHEJ complex includes PAXX (PubMed:25574025, 25941166). Following autophosphorylation, PRKDC dissociates from DNA (PubMed:33854234). Interacts with DNA-PKcs-interacting protein (KIP) with the region upstream the kinase domain (PubMed:9372844). PRKDC alone also interacts with and phosphorylates DCLRE1C, thereby activating the latent endonuclease activity of this protein (PubMed:11955432, 15071507, 14744996, 15456891, 15574326, 15811628, 15936993). Interacts with C1D (PubMed:9679063). Interacts with TTI1 and TELO2 (PubMed:20801936, 20427287, 20810650). Interacts with CIB1 (PubMed:9372844). Interacts with SETX (PubMed:23149945). Interacts with NR4A3; the DNA-dependent protein kinase complex DNA-PK phosphorylates and activates NR4A3 and prevents NR4A3 ubiquitination and degradation (PubMed:25852083). Interacts with BRAT1 (PubMed:22977523). Part of the HDP-RNP complex composed of at least HEXIM1, PRKDC, XRCC5, XRCC6, paraspeckle proteins (SFPQ, NONO, PSPC1, RBM14, and MATR3) and NEAT1 RNA (PubMed:28712728). Interacts with KAT5 (PubMed:32832608).
