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%[1] 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

Basolateral
