A carboxylate transporter is a membrane transport protein that transports carboxylate.
They are responsible for the reabsorption of filtered carboxylate in renal physiology, resulting in a 100% Page 799 reabsorption in the proximal tubule.
In proximal tubule In the renal proximal tubule, there are several kinds of carboxylate transporters in the apical membrane and the basolateral membrane.
Apical Na-monocarboxylate cotransporter 3Na-dicarboxylate cotransporter 3Na-tricarboxylate cotransporter
Basolateral H-monocarboxylate cotransporter organic anion-dicarboxylate exchanger
