Anti-PIGW antibodies are used in the immunodetection of the protein phosphatidylinositol glycan anchor biosynthesis class W. In humans, the canonical protein has a reported length of 504 amino acid residues and a mass of 56.9 kDa. Its subcellular localization is in the ER. A member of the PIGW protein family, PIGW is known to be required for the transport of GPI-anchored proteins to the plasma membrane. Post-translational modifications have been described, including glycosylation. The PIGW gene has been associated with the disease, Glycosylphosphatidylinositol biosynthesis defect. Synonyms for this target antigen include GPI-anchored wall protein transfer 1 homolog, and phosphatidylinositol-glycan biosynthesis class W protein. PIGW gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the PIGW antibodies listed below. In addition, ELISA is also a common application.
