Anti-VPS4B antibodies are used in the immunodetection of the protein vacuolar protein sorting 4 homolog B. In humans, the canonical protein has a reported length of 444 amino acid residues and a mass of 49.3 kDa. Its subcellular localization is in the membrane. It is ubiquitously expressed across many tissue types. A member of the AAA ATPase protein family, VPS4B is known to be involved in late steps of the endosomal multivesicular bodies (MVB) pathway. Synonyms for this target antigen include SKD1, SKD1B, VPS4-2, vacuolar protein sorting-associated protein 4B, cell migration-inducing 1, and MIG1. VPS4B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of VPS4B antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
