Protein

Mitochondrial uncoupling protein 2

Gene

UCP2

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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.

Polymorphismi

Genetic variations in UCP2 define the body mass index quantitative trait locus 4 (BMIQ4) [MIMi: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.
