Atm Gene Summary [Rat]
Predicted to enable identical protein binding activity and phosphotransferase activity, alcohol group as acceptor. Involved in several processes, including cellular response to ionizing radiation; positive regulation of DNA catabolic process; and regulation of microglial cell activation. Predicted to be located in chromosome, telomeric region; microtubule cytoskeleton; and nuclear lumen. Predicted to be part of DNA repair complex. Predicted to be active in nucleus; peroxisomal matrix; and site of double-strand break. Predicted to be extrinsic component of synaptic vesicle membrane. Used to study ataxia telangiectasia; disease of cellular proliferation; infertility; leukemia; and lymphoma. Biomarker of pre-malignant neoplasm and status epilepticus. 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]
