Anti-GABARAPL1 antibodies are used in the immunodetection of the protein GABA type A receptor associated protein like 1. In humans, the canonical protein has a reported length of 117 amino acid residues and a mass of 14 kDa. Its subcellular localization is in the cytoplasmic vesicles, ER, Golgi, 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 ATG8 protein family, GABARAPL1 is reported to be a ubiquitin-like modifier that increases cell-surface expression of kappa-type opioid receptor through facilitating anterograde intracellular trafficking of the receptor. Post-translational modifications have been described, including protein cleavage. Synonyms for this target antigen include APG8L, ATG8, ATG8B, ATG8L, GEC1, and APG8-LIKE. GABARAPL1 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Over 100 citations in the literature describe the use of GABARAPL1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
