dc.description.abstractThe clinically important Rh blood group system is complex, consisting of multiple distinct antigens. Despite clinical recognition for over 50 years, the Rh blood group antigens have remained poorly understood on a molecular level until the recent identification and characterization of the "Rh polypeptides," the core structural proteins of the Rh antigens. This group of erythrocyte membrane proteins of molecular weight 30,000-35,000 daltons was first recognized by employing Rh-specific antibodies to immunoprecipitate radiolabeled components of erythrocyte membranes. By using antibodies specific for the Rh D, c, and E antigens, a series of highly related non-identical proteins were immunoprecipitated, indicating that the Rh antigens are composed of multiple related proteins. The Rh polypeptides have been purified and characterized, and they were found to have several unusual biochemical characteristics. The Rh polypeptides penetrate the membrane bilayer; they are linked to the underlying membrane skeleton; they are covalently fatty acid acylated with palmitate. While the Rh antigenic reactivity is unique to human erythrocytes, the Rh polypeptides have been isolated from erythrocytes of diverse species and are thought to be fundamental components of all mammalian erythrocyte membranes. The functional role of the Rh polypeptides remains undefined, but a role in the organization of membrane phospholipid is suspected.en_US
