Anti-FBXO40 antibodies are used in the immunodetection of the protein F-box protein 40. In humans, the canonical protein has a reported length of 709 amino acid residues and a mass of 79.8 kDa. Its subcellular localization is in the cytoplasm. It is found to be preferentially expressed in the heart and skeletal muscle. FBXO40 is a suspected substrate-recognition component of the SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex that may function in myogenesis. Synonyms for this target antigen include F-box only protein 40, muscle disease-related protein, and FBX40. FBXO40 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some FBXO40 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in ELISA experiments, among other applications.
