Previous GeneCards Identifiers for UCP3 Gene
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. The different UCPs have tissue-specific expression; this gene is primarily expressed in skeletal muscle. This gene's protein product is postulated to protect mitochondria against lipid-induced oxidative stress. Expression levels of this gene increase when fatty acid supplies to mitochondria exceed their oxidation capacity and the protein enables the export of fatty acids from mitochondria. UCPs contain the three solcar protein domains typically found in MACPs. Two splice variants have been found for this gene.[provided by RefSeq, Nov 2008]
GeneCards Summary for UCP3 Gene
UCP3 (Uncoupling Protein 3) is a Protein Coding gene. Diseases associated with UCP3 include Obesity and Obesity, Ucp3-Related. Among its related pathways are Metabolism and Mitochondrial Uncoupling Proteins. GO annotations related to this gene include transporter activity and oxidative phosphorylation uncoupler activity. An important paralog of this gene is UCP2.
UniProtKB/Swiss-Prot for UCP3 Gene
UCP are mitochondrial transporter proteins that create proton leaks across the inner mitochondrial membrane, thus uncoupling oxidative phosphorylation. As a result, energy is dissipated in the form of heat. May play a role in the modulation of tissue respiratory control. Participates in thermogenesis and energy balance.
