Thermogenin
MAMMALIAN PROTEIN FOUND IN HOMO SAPIENS
Uncoupling protein 1; UCP1; UCP1 (gene); Uncoupling protein-1; SLC25A7
Thermogenin (called uncoupling protein by its discoverers and now known as uncoupling protein 1, or UCP1) is a mitochondrial carrier protein found in brown adipose tissue (BAT). It is used to generate heat by non-shivering thermogenesis, and makes a quantitatively important contribution to countering heat loss in babies which would otherwise occur due to their high surface area-volume ratio.
