Mitochondrial uncoupling protein 2

Gene

UCP2

Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
Status
Reviewed-Annotation score: -Experimental evidence at transcript 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 (By similarity).By similarity
