Anti-FAAP20 antibodies are used in the immunodetection of the protein FA core complex associated protein 20. In humans, the canonical protein has a reported length of 180 amino acid residues and a mass of 19.9 kDa. Its subcellular localization is in the nucleus. Up to 6 different isoforms have been reported for this protein. FAAP20 is a known component of the Fanconi anemia (FA) complex required to recruit the FA complex to DNA interstrand cross-links (ICLs) and promote ICLs repair. Synonyms for this target antigen include FANCA-associated protein of 20 kDa, Fanconi anemia core complex associated protein 20, Fanconi anemia-associated protein of 20 kDa, and Fanconi anemia core complex-associated protein 20. FAAP20 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of FAAP20 antibodies have been mentioned in research publications and have associated citations. Immunocytochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
