Citrate transporter that mediates the exchange of mitochondrial citrate for cytosolic malate (By similarity). Required for proper neuromuscular junction formation (PubMed:26870663). Morpholino-injected embryos display altered tail morphology, impaired swimming and defective touch-evoked escape responses. Neuromuscular junction development is abnormal and motor axon terminals show short and erratic outgrowth toward the muscle fiber with no evidence of complete synapse formation. In addition, knockdown embryos often show edema of the hindbrain, heart, yolk sac and tail. Belongs to the mitochondrial carrier (TC 2.A.29) family.
