The 53BP1 Antibody (CAB5757) is a high-quality antibody developed for reliable detection and analysis of target proteins. This gene encodes a protein that functions in the DNA double-strand break repair pathway choice, promoting non-homologous end joining (NHEJ) pathways, and limiting homologous recombination. This protein plays multiple roles in the DNA damage response, including promoting checkpoint signaling following DNA damage, acting as a scaffold for recruitment of DNA damage response proteins to damaged chromatin, and promoting NHEJ pathways by limiting end resection following a double-strand break. These roles are also important during V(D)J recombination, class switch recombination and at unprotected telomeres. Alternative splicing results in multiple transcript variants encoding different isoforms.
This antibody is validated for use in WB, IHC-P, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.
