    The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder. [provided by RefSeq, Aug 2010]

    Interaction

    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).
