PubMed (7797558): Olives B, Mattei MG, Huet M, Neau P, Martial S, Cartron JP, Bailly P. Kidd blood group and urea transport function of human erythrocytes are carriedby the same protein.J Biol Chem. 1995 Jun 30;270(26):15607-10. PMID: 7797558 [PubMed - indexed for MEDLINE]

The gene encoding the urea transporter of human erythrocytes (HUT11 clone) has been cloned recently (Olives, B., Neau, P., Bailly, P., Hediger, M. A., Rousselet, G., Cartron, J. P., and Ripoche, P. (1994) J. Biol. Chem. 269, 31649-31652). Now, this gene has been assigned to chromosome 18q12-q21 by in situ hybridization, as also found for the Kidd (Jk) blood group locus. In coupled transcription-translation assays, the HUT11 cDNA directed the synthesis of a 36-kDa protein which was immunoprecipitated by a human anti-Jk3 antibody produced by immunized Jk(a-b-) donors whose red cells lack Kidd antigens. The anti-Jk3 antibody also immunoprecipitated a protein material of 46-60 kDa from all red cell membranes, except those from Jk(a-b-) cells. After N-glycanase digestion the 46-60-kDa component was reduced to 36 kDa. A rabbit antibody raised against the predicted NH2-terminal amino-acids of the HUT11 protein reacted on immunoblots with a 46-60-kDa component present in all human erythrocytes except those from Jk(a-b-) individuals. Jk(a-b-) red cells lack the Kidd/urea transport protein and have a selective defect of the urea transport capacity, but a normal water permeability and aquaporin-associated Colton blood group antigens. These findings indicate that the erythrocyte urea transporter is encoded by the Kidd locus and may have implications for the biology of urea transporters and their tissue-specific regulation.
