Protein name: UCP2 (uncoupling protein 2) Aliases: proton carrier, UCPH Substrates: H+ Transport type: Facilitated transporter Tissue and cellular expression: lung, kidney, spleen, heart Subcellular expression: inner mitochondrial membrane Disease: obesity, type 2 diabetes, congenital hyperinsulinism Locus: 11q13 Sequence ID: NP_003346.2, NM_003355.2 Gene ID: 7351 Splice variants: N/D

UCP2_HUMAN (UniProt)

Gene names: UCP2, SLC25A8
Protein names and data: UCP2_HUMAN, Full=Mitochondrial uncoupling protein 2;Short=UCP 2, Full=Solute carrier family 25 member 8;Full=UCPH; Length: 309 a.a., Mass: 33229 Da,
fasta formatted sequence

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
Cellular 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

Genetic variants

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. See also Ensembl:ENST00000310473
