Predicted to enable pyruvate transmembrane transporter activity. Involved in pyruvate metabolic process. Acts upstream of with a positive effect on digestive tract development. Predicted to be located in membrane and mitochondrion. Predicted to be active in mitochondrial inner membrane. Is expressed in several structures, including digestive system; female organism; head; pectoral fin; and vasculature. Human ortholog(s) of this gene implicated in mitochondrial pyruvate carrier deficiency. Orthologous to human MPC1 (mitochondrial pyruvate carrier 1).
