ID:UCP2_HUMAN DESCRIPTION: RecName: Full=Mitochondrial uncoupling protein 2; Short=UCP 2; AltName: Full=Solute carrier family 25 member 8; AltName: Full=UCPH; FUNCTION: UCP are mitochondrial transporter proteins that create proton leaks across the inner mitochondrial membrane, thus uncoupling oxidative phosphorylation from ATP synthesis. As a result, energy is dissipated in the form of heat. SUBUNIT: Acts as a dimer forming a proton channel (By similarity). SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: Widely expressed in adult human tissues, including tissues rich in macrophages. Most expressed in white adipose tissue and skeletal muscle. POLYMORPHISM: Genetic variations in UCP2 define the body mass index quantitative trait locus 4 (BMIQ4) [MIM:607447]. A common polymorphism in the promoter of UCP2 has been shown to be associated with a decreased risk of obesity in middle-aged individuals. SIMILARITY: Belongs to the mitochondrial carrier family. SIMILARITY: Contains 3 Solcar repeats. WEB RESOURCE: Name=NIEHS-SNPs; URL="http://egp.gs.washington.edu/data/ucp2/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
