The Rh blood group system is one of the most polymorphic and immunogenic systems
known in humans. In the past decade, intense investigation has yielded considerable …

Rh (Rhesus) proteins (D, CcEe) are expressed in red cells (RBC) in association with other
membrane proteins (RhAG, LW, CD47 and GPB). By interacting with the spectrin-based …

The Rhesus blood-group antigens are defined by a complex association of membrane
polypeptides that includes the non-glycosylated Rh proteins (RhD and RhCE) and the RHag …

Biochemical and molecular genetic studies have revealed that blood group antigens are
present on cell surface molecules of wide structural diversity, including carbohydrate …

Ammonium transporters play a key functional role in nitrogen uptake and assimilation in
microorganisms and plants; however, little is known about their structural counterpart in …

In mammals, the Rh family includes the variable Rh polypeptides and invariant RhAG
glycoprotein. These polytopic proteins are confined to the erythroid lineage and are …

Rhesus (Rh) antigens are defined by a complex association of membrane polypeptides that
are missing or severely deficient from the red cells of rare Rhnullindividuals who suffer a …

The Rh (Rhesus) blood group system is the most complex of the known human blood group
polymorphisms. The expression of its antigens is controlled by a two-component genetic …

Renal ammonium (NH 3+ NH 4+) transport is a key process for body acid-base balance. It is
well known that several ionic transport systems allow NH 4+ transmembrane translocation …

A number of molecules on the surface of red blood cells (RBCs) and platelets express
antigenic activity. Various biochemical and molecular approaches have been used to …
