ATMIN (ATM Interactor) is a nuclear protein that serves as an essential cofactor for the ATM kinase, a key regulator of the DNA damage response (DDR). Initially identified as an ATM-binding partner, ATMIN facilitates ATM activation in response to replication stress and chromatin alterations, though its role is distinct from ATM’s canonical function in double-strand break (DSB) repair. ATMIN also acts as a transcriptional regulator, influencing genes involved in metabolism, hypoxia, and oxidative stress.

ATMIN antibodies are critical tools for studying its expression, localization, and interactions. They are widely used in techniques like Western blotting, immunofluorescence, and immunoprecipitation to explore ATMIN’s dual roles in DDR and transcriptional regulation. Research using these antibodies has revealed ATMIN’s involvement in maintaining genomic stability, with implications in cancer biology, neurodegenerative diseases, and developmental disorders.

Notably, ATMIN knockout studies highlight its importance in embryonic development and organogenesis. Dysregulation of ATMIN has been linked to pathologies such as breast cancer, lung fibrosis, and Fanconi anemia. Commercial ATMIN antibodies are typically validated for specificity across human, mouse, and rat samples, enabling cross-species comparative studies. Researchers rely on these reagents to dissect ATMIN’s context-dependent functions and its interplay with ATM, p53. and other DDR components.
