Anti-ATG101 antibodies are used in the immunodetection of the protein autophagy related 101. In humans, the canonical protein has a reported length of 218 amino acid residues and a mass of 25 kDa. Its subcellular localization is in the cytoplasm. It is notably widely expressed in many tissue types. A member of the ATG101 protein family, ATG101 is known to be an autophagy factor required for autophagosome formation. Synonyms for this target antigen include autophagy-related protein 101 and Atg13-interacting protein. ATG101 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ATG101 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
