Generates heat in infants
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. See more 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 See more UCP1 is expressed in brown adipose tissue, which is functionally found only in eutherians. The UCP1, or thermogenin, gene likely arose in an ancestor of modern vertebrates, but did not initially allow for our vertebrate ancestor to use non-shivering See more Methods of delivering UCP1 to cells by gene transfer therapy or methods of its upregulation have been an important line of enquiry in research into the treatment of obesity, due to their … See more • Macher, Gabriel; Koehler, Melanie; Rupprecht, Anne; Kreiter, Jürgen; Hinterdorfer, Peter; Pohl, Elena E.
