Anti-ABRAXAS1 antibodies are used in the immunodetection of the protein abraxas 1, BRCA1 A complex subunit. In humans, the canonical protein has a reported length of 409 amino acid residues and a mass of 46.7 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. A member of the FAM175 protein family, ABRAXAS1 is known to be involved in DNA damage response and double-strand break (DSB) repair. Post-translational modifications have been described, including phosphorylation. The ABRAXAS1 gene has been associated with the disease, Breast cancer. Synonyms for this target antigen include abraxas protein, coiled-coil domain containing 98, family with sequence similarity 175 member A, and BRCA1-A complex subunit Abraxas 1. ABRAXAS1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ABRAXAS1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
