Anti-VWA1 antibodies are used in the immunodetection of the protein von Willebrand factor A domain containing 1. In humans, the canonical protein has a reported length of 445 amino acid residues and a mass of 46.8 kDa. Its subcellular localization is in the extracellular matrix and is secreted. Up to 3 different isoforms have been reported for this protein. VWA1 is reported to promote matrix assembly (By similarity). Post-translational modifications have been described, including N-glycosylation. The VWA1 gene has been associated with the disease, Neuropathy. Synonyms for this target antigen include von Willebrand factor A domain-containing protein 1 and von Willebrand factor A domain-related protein. VWA1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some VWA1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
