The ATR (Ab-428) antibody is a monoclonal antibody specifically designed to target the Ataxia-Telangiectasia and Rad3-related (ATR) kinase, a critical serine/threonine protein kinase involved in DNA damage response (DDR) pathways. ATR plays a central role in maintaining genomic stability by sensing replication stress and coordinating cell cycle checkpoints, DNA repair, and apoptosis. It is activated by single-stranded DNA (ssDNA) arising from stalled replication forks or DNA damage, leading to phosphorylation of downstream targets like CHK1. which halts cell cycle progression to allow repair. Dysregulation of ATR is linked to cancer, neurodegenerative disorders, and resistance to chemotherapy or radiation.
The Ab-428 clone is commonly used in research to study ATR's function, expression, and interaction partners in cellular models. It is validated for applications such as Western blotting, immunoprecipitation, and immunofluorescence, often in studies exploring replication stress responses, cancer biology, and therapeutic targeting. ATR inhibitors, including those tested alongside Ab-428. are emerging as promising anticancer agents, particularly in tumors with defective homologous recombination repair (e.g., BRCA mutations). By suppressing ATR activity, these agents exacerbate genomic instability in cancer cells, sensitizing them to DNA-damaging therapies.
The antibody’s specificity for human ATR makes it a valuable tool for elucidating DDR mechanisms and evaluating ATR-targeted therapies in preclinical settings. Its development aligns with growing interest in exploiting DDR vulnerabilities for precision oncology.
