Protein-coding gene in the species Homo sapiens
Mitochondrial pyruvate carrier 2 (MPC2) also known as brain protein 44 (BRP44) is a protein that in humans is encoded by the MPC2 gene .[ 5] [ 6] [ 7] It is a member of the Mitochondrial Pyruvate Carrier (MPC) protein family .[ 8] This protein is involved in transport of pyruvate across the inner membrane of mitochondria in preparation for the pyruvate dehydrogenase reaction .[ 9]

Clinical significance [ edit ] Mutations in the MPC2 gene cause an autosomal recessive disease comparable to the symptoms of Mitochondrial pyruvate carrier deficiency (MPC1 gene).[ 10] The symptoms associated with mutations in the MPC2 gene include early-onset neurological problems, normal lactate/pyruvate ratio (however both lactate and pyruvate are in higher than normal concentrations), lactic acidosis, hypotonia, cardiomegaly, and facial dysmorphia.[ 10]
