Tricarboxylate transport protein, mitochondrial

Function

Mitochondrial electroneutral antiporter that exports citrate from the mitochondria into the cytosol in exchange for malate (PubMed:29031613, PubMed:29238895). Also able to mediate the exchange of citrate for isocitrate, phosphoenolpyruvate, cis-aconitate and to a lesser extend cis-aconitate, maleate and succinate (PubMed:29031613). In the cytoplasm citrate is important in the regulation of glycolysis through a feedback mechanism and in the production of acetyl-CoA which is needed for the synthesis of fatty acids, sterols, prostaglandins, dolichol and coenzyme Q (CoQ). Required for proper neuromuscular junction formation (Probable).

Involvement in disease

Combined D-2- and L-2-hydroxyglutaric aciduria

D2L2AD

An autosomal recessive neurometabolic disorder characterized by neonatal-onset encephalopathy with severe muscular weakness, intractable seizures, respiratory distress, and lack of psychomotor development resulting in early death. Brain imaging shows abnormalities including enlarged ventricles, delayed myelination, and germinal layer cysts.

None

The disease is caused by variants affecting the gene represented in this entry.

Myasthenic syndrome, congenital, 23, presynaptic

CMS23

A form of congenital myasthenic syndrome, a group of disorders characterized by failure of neuromuscular transmission, including pre-synaptic, synaptic, and post-synaptic disorders that are not of autoimmune origin. Clinical features include easy fatigability and muscle weakness. CMS23 inheritance is autosomal recessive.

None

The disease is caused by variants affecting the gene represented in this entry.

Post-translational modifications

Possesses a short cleavable presequence, which, however, is found to be dispensable both for targeting to mitochondria and insertion into the inner membrane. However, the presequence is required to keep SLC25A1 in a soluble state and thus in an import-competent state. Mature SLC25A1 lacking the presequence is prone to aggregation.

Sequence similarities

Belongs to the mitochondrial carrier (TC 2.A.29) family.
