Atm Gene Summary [Mouse]
Enables histone H2AXS139 kinase activity. Involved in several processes, including cellular response to retinoic acid; negative regulation of TORC1 signaling; and regulation of macromolecule biosynthetic process. Acts upstream of or within several processes, including immune system development; intracellular signal transduction; and meiotic nuclear division. Located in cytoplasm; microtubule cytoskeleton; and nucleus. Is extrinsic component of synaptic vesicle membrane. Is expressed in several structures, including alimentary system; genitourinary system; hemolymphoid system; nervous system; and sensory organ. Used to study ataxia telangiectasia. Human ortholog(s) of this gene implicated in several diseases, including breast cancer (multiple); endocrine gland cancer (multiple); lung carcinoma (multiple); neurodegenerative disease (multiple); and senile cataract. Orthologous to human ATM (ATM serine/threonine kinase). [provided by Alliance of Genome Resources, Jul 2025]
