Rh family, B glycoprotein, also known as RHBG, is an ammonia transporter protein which in humans is encoded by the RHBG gene.^[5]^[6]

Function

RHBG and RHCG are non-erythroid members of the Rhesus (Rh) protein family that are mainly expressed in the kidney and belong to the methylammonium-ammonium permease/ammonia transporters superfamily. Rh family proteins are all predicted to be transmembrane proteins with 12 membrane spanning domains and intracytoplasmic N- and C-termini.^[5]

<span class="mw-page-title-main">Ammonia transporter</span>

Ammonia transporters are structurally related membrane transport proteins called Amt proteins in bacteria and plants, methylammonium/ammonium permeases (MEPs) in yeast, or Rhesus (Rh) proteins in chordates. In humans, the RhAG, RhBG, and RhCG Rhesus proteins constitute solute carrier family 42 whilst RhD and RhCE form the Rh blood group system. The three-dimensional structure of the ammonia transport protein AmtB from Escherichia coli has been determined by x-ray crystallography revealing a hydrophobic ammonia channel. The human RhCG ammonia transporter was found to have a similar ammonia-conducting channel structure. It was proposed that the erythrocyte Rh complex is a heterotrimer of RhAG, RhD, and RhCE subunits in which RhD and RhCE might play roles in anchoring the ammonia-conducting RhAG subunit to the cytoskeleton. Based on reconstitution experiments, purified RhCG subunits alone can function to transport ammonia. RhCG is required for normal acid excretion by the mouse kidney and epididymis.
