The sodium-dicarboxylate cotransporters (Solute carrier family 13) , which transport succinate and other Krebs cycle intermediates, fall into 2 categories based on their substrate affinity, low affinity and high affinity. Both the low- and high-affinity transporters play an important role in the handling of citrate by the kidneys. The two different Na+-coupled dicarboxylate transporters (NADC) have been identified in mammalian tissues. These are NADC1and NADC3 (NADC2 is found in C. Elegans). NADC1 is Na+-coupled, electrogenic, and exhibits low affinity for its dicarboxylatesubstrates. This isoform is expressedprimarily in the brush border membrane of intestinal and renalepithelial cells. The physiological function of NADC1 is to absorbthe intermediates of the citric acid cycle, such as citrate, succinate,-ketoglutarate, fumarate, and malate, in the intestine and kidney.NADC3 is also a Na+-coupled and electrogenic dicarboxylate transporter, but it exhibitsrelatively higher affinity for its substrates compared with NADC1. The NADC3is expressed primarily in the basolateral membrane of intestinaland renal epithelial cells. However, it is also found in tissuessuch as liver, placenta, and brain. NADC3 in the kidney is involvedin generating the driving force for the organic anion transporterOAT1 to facilitate the active entry of organic anions into thetubular cells across the basolateral membrane. In the brain,NADC3 mediates the cellular uptake of N-acetylaspartate, a processclosely linked to myelination. Therefore, the physiologicalfunctions of the NADCs may extend beyond the mediation of cellularentry of citric acid cycle intermediates. Recently, a third member of this familyin mammals has been identified, Na+-coupled citrate transporter (NACT), mediates the cellular uptakeof citrate in a Na+-coupled manner. NACT, is 568aa protein in human (chr 17p13.2) and 572aa in rat, NaCT is expressed in liver, testis and brain in rat and shows preference for citrate over dicarboxylates, it may play a role in cellular utilization of citrate in blood for the synthesis of fatty acids and cholesterol and for the generation of energy.
