Carboxylate transporter

From Wikipedia, the free encyclopedia

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.

[edit] In proximal tubule

In the renal proximal tubule, there are several kinds of carboxylate transporters in the apical membrane and the basolateral membrane.

[edit] Apical

  • Na-monocarboxylate cotransporter
  • 3Na-dicarboxylate cotransporter
  • 3Na-tricarboxylate cotransporter

[edit] Basolateral

  • H-monocarboxylate cotransporter[1]
  • organic anion-dicarboxylate exchanger
