Abstract: gpD protein, the major subunit of the Duffy blood group antigenic system, has been isolated. gpD protein contains the receptor, by which P. vivax enters red cells and causes malaria. gpD has significant sequence homology with human and rabbit interleukin-8 receptors and, therefore, gpD protein likely is a new class of chemoattractant cytokines receptor. gpD protein cDNA has a quasi-total homology with a human hippocampus cDNA clone HHCMF86 and, therefore, gpD protein or a homologous protein may be present as a neuropeptide receptor in brain. gpD protein is present in all red cell progenitors and it may be a receptor for cell proliferation and/or differentiation. gpD protein cDNA identifies in human kidney a mRNA of the same size as the bone marrow. Since the kidney is not and has no potential to become an erythropoietic organ, this putative chemoattractant receptor may have essential renal functions.
