26354748 We characterized ammonia and ammonium (NH3/NH4 (+)) transport by the rhesus-associated (Rh) glycoproteins RhAG, Rhbg, and Rhcg expressed in Xenopus oocytes. We used ion-selective microelectrodes and two-electrode voltage clamp to measure changes in intracellular pH, surface pH, and whole cell currents induced by NH3/NH4 (+) and methyl amine/ammonium (MA/MA(+)).
26175207 novel allele in a Brazilian pregnant woman encoding the Rhnull phenotype due to a change in RHAG exon2 c.310C>T, which leads to a premature stop codon (Gln104Stop).
25296744 A new Rh null allele (RHAG*01N.13) of the regulator type found in a consanguineous French-speaking quebecers'family.
24077989 RhAG, RhBG and RhCG-exhibit significant permeability to NH3 and show for the first time that RhBG and RhCG can conduct CO2.
23417980 Data from differentiating cultured erythroid precursor cells suggest that RhAG knockdown abolishes Rh blood group expression (RhoD [ras homolog family member D]; ICAM4 [intercellular adhesion molecule 4]; CD47 Rh-related antigen) in erythroid cells.
22012326 Results provide new insights into the functional impact of the Phe65Ser mutation in RhAG.
21883272 Substitution of GPB with Gp.Mur significantly reduced the expression of Rh antigen and RhAG on the Mi.III(+/+) erythrocyte membrane
21849667 The results provide new insight into RhAG stomatocytosis mutant F65S as a combined loss-of-function/gain-of-function mutation for methylammonium/methylammonium+ transport
21682734 that the 672C>A missense mutation in the RHAG gene could result in Rh(null) of the regulator type, and the single-amino-acid change (Ser to Arg) might be critical for assembly of the Rh antigen complex within the membrane
19273840 gas channels exhibit selectivity for CO(2) vs. NH(3) permeability, demonstrating the sequence AQP4 congruent with AQP5 > AQP1 > AmtB > RhAG.
18931342 Reduced amounts of Rh-associated glycoprotein is associated with overhydrated hereditary stomatocytosis.
17712059 Rh protein, presumably the Rh-associated glycoprotein RhAG, possesses a gas channel that allows passage of CO2 in addition to NH3
16574458 Review. RhAG plays a major role in the NH3 conductance of erythrocytes, but probably not in CO2 transport.
16564724 RhAG expression enhanced the ammonium-induced initial alkalinization (related to NH3 influx)& secondary acidification (related to NH4+ influx). Sub-millimolar NH4+ concentrations induced inward currents in voltage-clamped RhAG-expressing cells.
16563829 RhAG-mediated transport is an electroneutral process that is driven by the NH4+ concentration and the transmembrane H+ gradient, effectively exchanging NH4+ for H+ in a process that results in transport of net NH3.
16378686 Observational study of gene-disease association. (HuGE Navigator)
16378686 The combination of these polymorphisms could not be found in any control individuals, suggesting that they might be involved in genetic predisposition to migraine in this family.
15572441 RhAG facilitates CH(3)NH(2)/NH(3) movement across the RBC membrane and represents a potential example of a gas channel in mammalian cells.
14966114 RhAG functions as a NH(4)(+)/H(+) exchanger; ammonium transport is coupled to the H(+) gradient
12393442 interactions of CD47 and RhAG and the Rh proteins with one another and with the cytoskeleton of intact erythrocytes
12130520 Cell-surface expression of RhD blood group polypeptide is posttranscriptionally regulated by the RhAG glycoprotein.
