Recombinant human Rh family C glycoprotein (RHCG) is a genetically engineered protein that plays a critical role in ammonium transport and acid-base homeostasis. As a member of the Rh solute carrier family, RHCG is primarily expressed in the kidneys, particularly in the collecting ducts and intercalated cells, where it facilitates NH₃/NH₄⁺ excretion to regulate systemic pH. Unlike its homolog RhAG (associated with erythrocyte membranes), RHCG is integral to renal ammoniagenesis, helping to maintain nitrogen balance and counteract metabolic acidosis.
Produced via recombinant DNA technology, RHCG is typically expressed in mammalian cell lines (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications and membrane localization. Purification methods often involve affinity chromatography tags (e.g., His-tag) followed by functional validation through transport assays. Researchers utilize recombinant RHCG to study its structure-function relationships, including pH-sensitive gating mechanisms and interactions with other transport proteins like NBCe1 or pendrin.
Aberrant RHCG expression or mutations are linked to renal tubular acidosis and progressive kidney disease. Its recombinant form has become essential for developing targeted therapies and diagnostic biomarkers for acid-base disorders. Current studies also explore its potential in bioengineering artificial renal systems and ammonia-sensitive biosensors.
