Anti-VPS18 core subunit of CORVET and HOPS complexes antibodies are used for the immunodetection of the protein encoded by the VPS18 gene. In humans, the canonical protein has a reported length of 973 amino acid residues and a mass of 110.2 kDa. Its subcellular localization is in the cytoplasmic vesicles, lysosomes, and membrane. It is ubiquitously expressed across many tissue types. A member of the VPS18 protein family, it is reported to play a role in vesicle-mediated protein trafficking to lysosomal compartments including the endocytic membrane transport and autophagic pathways. Other names for this target antigen include VPS18, CORVET/HOPS core subunit, hVPS18, vacuolar protein sorting 18 homolog, vacuolar protein sorting protein 18, and vacuolar protein sorting-associated protein 18 homolog. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
