Anti-VPS4A antibodies are used in the immunodetection of the protein vacuolar protein sorting 4 homolog A. In humans, the canonical protein has a reported length of 437 amino acid residues and a mass of 48.9 kDa. Its subcellular localization is in the membrane and cytoplasm. It is ubiquitously expressed across many tissue types. A member of the AAA ATPase protein family, VPS4A is known to be involved in late steps of the endosomal multivesicular bodies (MVB) pathway. The VPS4A gene has been associated with the disease, CIMDAG syndrome. Synonyms for this target antigen include SKD1, SKD1A, SKD2, VPS4, VPS4-1, vacuolar protein sorting-associated protein 4A, SKD1-homolog, and CIMDAG. VPS4A gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of VPS4A antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
