Citrin Antibody / ARALAR2 / SLC25A13

Citrin also known as solute carrier family 25, member 13 (also called Citrin and ARALAR-related gene 2) is a protein which in humans is encoded by the SLC25A13 gene. This gene is a member of the mitochondrial carrier family. The encoded protein contains four EF-hand Ca(2+) binding motifs in the N-terminal domain, and localizes to mitochondria. The protein catalyzes the exchange of aspartate for glutamate and a proton across the inner mitochondrial membrane, and is stimulated by calcium on the external side of the inner mitochondrial membrane. Mutations in this gene result in citrullinemia, type II. Multiple transcript variants encoding different isoforms have been found for this gene.
