Anti-ATP6V0B antibodies are used in the immunodetection of the protein ATPase H+ transporting V0 subunit b. In humans, the canonical protein has a reported length of 205 amino acid residues and a mass of 21.4 kDa. Its subcellular localization is in the cytoplasmic vesicles. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the V-ATPase proteolipid subunit protein family, ATP6V0B is known to be involved with autophagy pathways. Synonyms for this target antigen include HATPL, VMA16, V-type proton ATPase 21 kDa proteolipid subunit c'', ATPase, H+ transporting, lysosomal 21kDa, V0 subunit b, and ATP6F. ATP6V0B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the ATP6V0B antibodies listed below. ELISA and Immunohistochemistry are also common applications.
