Rhnull erythrocytes, which lack Rh proteins, are stomatocytic and spherocytic, and affected individuals have hemolytic anemia. 4 Recent findings indicate that Rh proteins mediate key interactions with the underlying cytoskeleton through protein 4.2 and ankyrin. 5-7These data suggest that Rhnull redblood cells, although serologically distinct, possess an Rh-like protein that is structurally very similar toRh(D) and Rh(c). The Rh D, E/e, and C/c blood group antigens are carried by three related but distinct membrane polypeptides (1-5) of approximately 32 kDa each (6, 7).
