FUNCTION: Serine/threonine protein kinase which activates checkpoint signaling upon double strand breaks (DSBs), apoptosis and genotoxic stresses such as ionizing ultraviolet A light (UVA), thereby acting as a DNA damage sensor (PubMed:9733514, PubMed:10550055, PubMed:10839545, PubMed:10910365, PubMed:12556884, PubMed:14871926, PubMed:15456891, PubMed:15448695, PubMed:15916964, PubMed:17923702). Recognizes the substrate consensus sequence [ST]-Q (PubMed:9733514, PubMed:10550055, PubMed:10839545, PubMed:10910365, PubMed:12556884, PubMed:14871926, PubMed:15456891, PubMed:15448695, PubMed:15916964, PubMed:17923702). Phosphorylates 'Ser-139' of histone variant H2AX at double strand breaks (DSBs), thereby regulating DNA damage response mechanism (By similarity). Also plays a role in pre-B cell allelic exclusion, a process leading to expression of a single immunoglobulin heavy chain allele to enforce clonality and monospecific recognition by the B-cell antigen receptor (BCR) expressed on individual B-lymphocytes. After the introduction of DNA breaks by the RAG complex on one immunoglobulin allele, acts by mediating a repositioning of the second allele to pericentromeric heterochromatin, preventing accessibility to the RAG complex and recombination of the second allele. Also involved in signal transduction and cell cycle control. May function as a tumor suppressor. Necessary for activation of ABL1 and SAPK. Phosphorylates DYRK2, CHEK2, p53/TP53, FBXW7, FANCD2, NFKBIA, BRCA1, CTIP, nibrin (NBN), TERF1, UFL1, RAD9, UBQLN4 and DCLRE1C (PubMed:9843217, PubMed:9733515, PubMed:10550055, PubMed:10766245, PubMed:10839545, PubMed:10910365, PubMed:10802669, PubMed:10973490, PubMed:11375976, PubMed:12086603, PubMed:15456891, PubMed:19965871, PubMed:30612738, PubMed:30886146, PubMed:26774286). May play a role in vesicle and/or protein transport. Could play a role in T-cell development, gonad and neurological function. Plays a role in replication-dependent histone mRNA degradation. Binds DNA ends. Phosphorylation of DYRK2 in nucleus in response to genotoxic stress prevents its MDM2-mediated ubiquitination and subsequent proteasome degradation (PubMed:19965871). Phosphorylates ATF2 which stimulates its function in DNA damage response (PubMed:15916964). Phosphorylates ERCC6 which is essential for its chromatin remodeling activity at DNA double-strand breaks (PubMed:29203878). Phosphorylates TTC5/STRAP at 'Ser-203' in the cytoplasm in response to DNA damage, which promotes TTC5/STRAP nuclear localization (PubMed:15448695). Also involved in pexophagy by mediating phosphorylation of PEX5: translocated to peroxisomes in response to reactive oxygen species (ROS), and catalyzes phosphorylation of PEX5, promoting PEX5 ubiquitination and induction of pexophagy (PubMed:26344566). {ECO:0000250|UniProtKB:Q62388, ECO:0000269|PubMed:10550055, ECO:0000269|PubMed:10766245, ECO:0000269|PubMed:10802669, ECO:0000269|PubMed:10839545, ECO:0000269|PubMed:10910365, ECO:0000269|PubMed:10973490, ECO:0000269|PubMed:11375976, ECO:0000269|PubMed:12086603, ECO:0000269|PubMed:12556884, ECO:0000269|PubMed:14871926, ECO:0000269|PubMed:15448695, ECO:0000269|PubMed:15456891, ECO:0000269|PubMed:15916964, ECO:0000269|PubMed:16086026, ECO:0000269|PubMed:16858402, ECO:0000269|PubMed:17923702, ECO:0000269|PubMed:19431188, ECO:0000269|PubMed:19965871, ECO:0000269|PubMed:26344566, ECO:0000269|PubMed:26774286, ECO:0000269|PubMed:29203878, ECO:0000269|PubMed:30612738, ECO:0000269|PubMed:30886146, ECO:0000269|PubMed:9733514, ECO:0000269|PubMed:9733515, ECO:0000269|PubMed:9843217}.

SUBUNIT: Homodimer (PubMed:28508083). Dimers or tetramers in inactive state. On DNA damage, autophosphorylation dissociates ATM into monomers rendering them catalytically active. Binds p53/TP53, ABL1, BRCA1, NBN/nibrin and TERF1. Part of the BRCA1-associated genome surveillance complex (BASC), which contains BRCA1, MSH2, MSH6, MLH1, ATM, BLM, PMS2 and the RAD50-MRE11-NBN protein complex. This association could be a dynamic process changing throughout the cell cycle and within subnuclear domains. Interacts with RAD17; DNA damage promotes the association. Interacts with EEF1E1; the interaction, induced on DNA damage, up-regulates TP53. Interacts with DCLRE1C, KAT8, KAT5, NABP2, ATMIN and CEP164. Interacts with AP2B1 and AP3B2; the interaction occurs in cytoplasmic vesicles (By similarity). Interacts with TELO2 and TTI1. Interacts with DDX1. Interacts with BRAT1. Interacts with CYREN (via XLF motif) (By similarity). Interacts (via microbody targeting signal) with PEX5; promoting translocation to peroxisomes in response to reactive oxygen species (ROS) (PubMed:26344566). {ECO:0000250|UniProtKB:Q62388, ECO:0000269|PubMed:11418864, ECO:0000269|PubMed:12556884, ECO:0000269|PubMed:14871926, ECO:0000269|PubMed:15456891, ECO:0000269|PubMed:15680327, ECO:0000269|PubMed:15923642, ECO:0000269|PubMed:16141325, ECO:0000269|PubMed:17525732, ECO:0000269|PubMed:18283122, ECO:0000269|PubMed:18449195, ECO:0000269|PubMed:18710941, ECO:0000269|PubMed:20427287, ECO:0000269|PubMed:20801936, ECO:0000269|PubMed:20810650, ECO:0000269|PubMed:22977523, ECO:0000269|PubMed:26344566, ECO:0000269|PubMed:28508083, ECO:0000269|PubMed:9168117, ECO:0000269|PubMed:9707615, ECO:0000269|PubMed:9843217}.
Post-translational modification
