Anti-LOXL3 antibodies are used in the immunodetection of the protein lysyl oxidase like 3. In humans, the canonical protein has a reported length of 753 amino acid residues and a mass of 83.2 kDa. Its subcellular localization is in the nucleus, cytoplasm, and is also secreted. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of a the Lysyl oxidase protein family, LOXL3 is reported to be a protein-lysine 6-oxidase that mediates the oxidation of peptidyl lysine residues to allysine in target proteins. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include lysyl oxidase homolog 3 and lysyl oxidase-like protein 3.
