Tricarboxylate transport protein, mitochondrial is a protein that in humans is encoded by the SLC25A1 gene. The mitochondrial tricarboxylate transporter (also called citrate transport protein, or CTP) is responsible for the movement of citrate across the mitochondrial inner membrane (Kaplan et al., 1993 [PubMed 8514800]).[supplied by OMIM].
Involved in citrate-H(+)/malate exchange. Important for the bioenergetics of hepatic cells as it provides a carbon source for fatty acid and sterol biosyntheses, and NAD+ for the glycolytic pathway.
