The XRCC4 (X-ray repair cross-complementing protein 4) antibody is a critical tool for studying DNA repair mechanisms, particularly non-homologous end joining (NHEJ), a primary pathway for repairing DNA double-strand breaks (DSBs) in mammalian cells. XRCC4 is a scaffolding protein essential for NHEJ, functioning as a stabilizing partner for DNA ligase IV to facilitate the final ligation step of broken DNA ends. It also interacts with other core NHEJ components, such as Ku70/Ku80 and XLF, forming dynamic complexes that maintain genomic stability. Dysregulation of XRCC4 is linked to genomic instability, immunodeficiency, and cancer predisposition.
XRCC4 antibodies are widely used in molecular biology and cancer research to detect protein expression, localization, and interactions. They enable techniques like Western blotting, immunofluorescence, and immunoprecipitation to investigate XRCC4's role in DNA repair fidelity, cellular responses to ionizing radiation or chemotherapeutic agents, and its association with diseases. Both polyclonal and monoclonal antibodies are available, often validated for specificity across human, mouse, and rat models. Researchers also utilize these antibodies to explore XRCC4 mutations or deletions in cancer genomes, providing insights into tumorigenesis and therapeutic resistance. As DSB repair pathways gain attention in targeted cancer therapies, XRCC4 antibodies remain pivotal for elucidating NHEJ mechanisms and developing biomarkers or treatment strategies.
