Ucp2 [Search on AGR]
Rattus norvegicus Predicted to enable several functions, including C4-dicarboxylate transmembrane transporter activity; inorganic anion transmembrane transporter activity; and protein homodimerization activity. Involved in several processes, including cellular response to lead ion; liver regeneration; and negative regulation of insulin secretion involved in cellular response to glucose stimulus. Predicted to be located in mitochondrial membrane. Used to study hypertension; non-alcoholic fatty liver disease; transient cerebral ischemia; and type 2 diabetes mellitus. Biomarker of congestive heart failure; fatty liver disease (multiple); hypothyroidism; obstructive jaundice; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in carotid artery disease; diabetic neuropathy; end stage renal disease; hypertension; and obesity. Orthologous to human UCP2 (uncoupling protein 2); PARTICIPATES IN forkhead class A signaling pathway; INTERACTS WITH (+)-catechin; (R)-lipoic acid; (R)-noradrenaline.

Homo sapiens Mitochondrial uncoupling proteins (UCP) are members of the larger family of mitochondrial anion carrier proteins (MACP). UCPs separate oxidative phosphorylation from ATP synthesis with energy dissipated as heat, also referred to as the mitochondrial proton leak. UCPs facilitate the transfer of anions from the inner to the outer mitochondrial membrane and the return transfer of protons from the outer to the inner mitochondrial membrane. They also reduce the mitochondrial membrane potential in mammalian cells. Tissue specificity occurs for the different UCPs and the exact methods of how UCPs transfer H+/OH- are not known. UCPs contain the three homologous protein domains of MACPs. This gene is expressed in many tissues, with the greatest expression in skeletal muscle. It is thought to play a role in nonshivering thermogenesis, obesity and diabetes. Chromosomal order is 5'-UCP3-UCP2-3'. [provided by RefSeq, Jul 2008]
