Anti-ATG12 antibodies are used in the immunodetection of the protein autophagy related 12. In humans, the canonical protein has a reported length of 140 amino acid residues and a mass of 15.1 kDa. Its subcellular localization is in the membrane and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the ATG12 protein family, ATG12 is known to be a ubiquitin-like protein involved in autophagy vesicles formation. Post-translational modifications have been described, including acetylation. Synonyms for this target antigen include APG12L, FBR93, HAPG12, ubiquitin-like protein ATG12, APG12 autophagy 12-like, and APG12. ATG12 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chicken species. Over 660 citations in the literature describe the use of ATG12 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
