RHAG Rh associated glycoprotein [Homo sapiens (human)] - Gene

Summary

Official Symbol: RHAGprovided by HGNC
Official Full Name: Rh associated glycoproteinprovided by HGNC
Primary source: HGNC:HGNC:10006
See related: Ensembl:ENSG00000112077 MIM:180297; AllianceGenome:HGNC:10006
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: OHS; RH2; OHST; RHNR; Rh50; CD241; RH50A; Rh50GP; SLC42A1
Summary: The protein encoded by this gene is erythrocyte-specific and is thought to be part of a membrane channel that transports ammonium and carbon dioxide across the blood cell membrane. The encoded protein appears to interact with Rh blood group antigens and Rh30 polypeptides. Defects in this gene are a cause of regulator type Rh-null hemolytic anemia (RHN), or Rh-deficiency syndrome.[provided by RefSeq, Mar 2009]

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(+)).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
