Background: ATM

ATM (ataxia telangiectasia mutated kinase) is the master regulator of the DNA double-strand break (DSB) repair pathway. This ubiquitously expressed serine/threonine protein kinase belongs to the PI3K-like family of proteins and responds to DSBs caused by oxidative and other genotoxic stresses (1). In addition to regulating the DNA damage response, ATM participates in vesicle and protein transport, T-cell development, gonads/neurological function, pre-B cell allelic exclusion, cell cycle control, and acts as a tumor suppressor (2,3). Defects in ATM are associated with ataxia telangiectasia (AT), T-cell acute lymphoblastic leukemia (TALL), T-prolymphocytic leukemia (TPLL), and B-cell non-Hodgkin lymphomas (BNHL) including mantle cell lymphoma (MCL) and B-cell chronic lymphocytic leukemia (BCLL) (4).

The theoretical molecular weight of ATM is 350 kDa and it has 3 main domains: a FAT (focal adhesion targeting) domain (aa 1960-2566), a PI-3/PI-4 kinase catalytic domain (aa 2712-2962), and a C-terminal FAT domain (aa 3024-3056). ATM exists as a dimer or tetramer in its inactive state. Upon sensing DNA damage, the MRE11-RAD50-NBS1 (MRN) complex recruits ATM. The intricate process of ATM activation involves acetylation by KAT5/TIP60, autophosphorylation at Ser-1981, and dissociation into catalytically active monomers (5). Following activation, ATM phosphorylates multiple substrates such as p53/TP53 and Chk2 involved in DNA repair, checkpoint signaling, and the apoptosis pathway.
