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]
A study in pediatric burn patients demonstrated that the UCP2 gene expression was significantly upregulated in skeletal muscle following injury, suggesting its involvement in post-burn mitochondrial dysfunction [TzikA et al. DOI:10.3892/ijmm_00000244]. In a mouse model of spinal cord injury, the UCP2 was expressed at higher levels in monocyte-derived macrophages compared to microglia, indicating a cell-type-specific role in the acute inflammatory response [Stewart et al. DOI:10.1186/s12974-021-02161-8]. A study in human pediatric burn patients demonstrated that the UCP2 gene expression was significantly upregulated (P=0.008) in skeletal muscle biopsies taken within 10 days of injury, suggesting its involvement in post-burn mitochondrial dysfunction [Tzika et al. DOI:10.3892/ijmm_00000244].
