SLC25A10 (DIC) is the mitochondrial dicarboxylate carrier, a member of the SLC25 mitochondrial carrier family. It is a multi-pass integral protein of the mitochondrial inner membrane that catalyzes the electroneutral antiport (exchange) of dicarboxylates (malate, succinate, malonate) and inorganic sulfur-containing anions (sulfate, thiosulfate) against inorganic phosphate across the inner membrane. Transport proceeds by a ping-pong mechanism in which one substrate is translocated and released before the counter-substrate binds, and the protein functions as a monomer. By exporting mitochondrial malate to the cytosol in exchange for phosphate, DIC supplies carbon skeletons and reducing equivalents for gluconeogenesis, fatty-acid synthesis, urea synthesis and sulfur metabolism, and is expressed most highly in liver and kidney. It does not transport glutathione. Biallelic loss-of-function mutations in SLC25A10 cause an autosomal-recessive mitochondrial DNA depletion syndrome (MTDPS19) with epileptic encephalopathy and respiratory complex I deficiency.

summary: >-
Derived from Reactome pathway participation (DIC provides the
dicarboxylate/sulfate antiport step that lets sulfate exit mitochondria in the
sulfide-oxidation pathway). DIC does not itself perform sulfide oxidation, which
is a pathway-level process carried out by oxidoreductases; this is an
over-annotation of the transporter to a downstream pathway.
