Anti-FBXO32 antibodies are used in the immunodetection of the protein F-box protein 32. In humans, the canonical protein has a reported length of 355 amino acid residues and a mass of 41.6 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is notably expressed in cardiac and skeletal muscle. FBXO32 is reported to be a substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Synonyms for this target antigen include atrogin 1, muscle atrophy F-box protein, and F-box only protein 32.
