Anti-LAP3 antibodies are used in the immunodetection of the protein leucine aminopeptidase 3. In humans, the canonical protein has a reported length of 519 amino acid residues and a mass of 56.2 kDa. Its subcellular localization is in the cytoplasm. It is notably widely expressed in many tissue types. A member of the Peptidase M17 protein family, LAP3 is reported to be a cytosolic metallopeptidase that catalyzes the removal of unsubstituted N-terminal hydrophobic amino acids from various peptides. Synonyms for this target antigen include LAP, PEPS, cytosol aminopeptidase, cysteinylglycine-S-conjugate dipeptidase, and HEL-S-106. LAP3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of LAP3 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.
