PIGH Antibody

Structure and Function of the PIGH Protein

The PIGH protein is a subunit of the GPI N-acetylglucosaminyltransferase complex, responsible for transferring N-acetylglucosamine to phosphatidylinositol during GPI-anchor assembly . It localizes to the endoplasmic reticulum membrane and interacts with other GPI-GnT complex components to initiate GPI-anchor biosynthesis . Dysregulation of PIGH has been implicated in diseases like paroxysmal nocturnal hemoglobinuria (PNH) and neurological disorders .

Applications of the PIGH Antibody

The antibody is primarily used in molecular and cellular biology research to study GPI-anchor biosynthesis and its role in disease. Key applications include:

• Western blot (WB): Detects PIGH in human and mouse tissues (e.g., kidney, liver) .

• ELISA: Quantifies PIGH levels in cell lysates or biological fluids .

• Immunohistochemistry: Localizes PIGH in cellular compartments (e.g., ER membrane) .

• Disease research: Investigates GPI-anchor defects in PNH and neurological disorders .

Research Findings

• Disease association: PNH patients exhibit mutations in GPI-anchor biosynthesis genes, including PIGH. Antibodies like PACO35450 enable detection of PIGH dysfunction in PNH models .

• Xenotransplantation: Studies using anti-pig antibodies (e.g., in porcine models) highlight the role of GPI anchors in immune tolerance, with implications for xenotransplantation .

• Therapeutic targeting: Anti-CD14 antibodies (e.g., rMil2) in porcine models demonstrate reduced Fc-mediated effects, suggesting GPI-anchor modulation could enhance therapeutic efficacy .
