Substrate fluxes in brown adipocytes upon adrenergic stimulation and uncoupling protein 1 ablation [PDF]
Quantification of substrate fluxes in brown adipocytes clarifies contributors to extracellular acidification, identifies a futile cycle of lipolysis and re-esterification, and suggests a role for glycogen during activation.

Association of Uncoupling Protein 1 (UCP1) gene polymorphism with obesity: a case-control study [PDF]
Background Obesity is one of the main causes of morbidity and mortality worldwide. More than 120 genes have been shown to be associated with obesity related phenotypes.

Proton conductance by human uncoupling protein 1 is inhibited by purine and pyrimidine nucleotides [PDF]
Uncoupling protein 1 (UCP1, SLC25A7) is responsible for the thermogenic properties of brown adipose tissue. Upon fatty acid activation, UCP1 facilitates proton leakage, dissipating the mitochondrial proton motive force to release energy as heat.

In silico identification of lipid-binding α helices of uncoupling protein 1. [PDF]
Uncoupling protein 1 (UCP1) located at the mitochondrial inner membrane serves an important role in adaptive non-shivering thermogenesis. Previous data has demonstrated that membrane lipids regulate the biological functions of membrane proteins. However, how mitochondrial lipids interact with UCP1 still remains elusive.

Structural mechanisms of mitochondrial uncoupling protein 1 regulation in thermogenesis [PDF]
In mitochondria, the oxidation of nutrients is coupled to ATP synthesis by the generation of a protonmotive force across the mitochondrial inner membrane. In mammalian brown adipose tissue (BAT), uncoupling protein 1 (UCP1, SLC25A7), a member of the SLC25 mitochondrial carrier family, dissipates the protonmotive force by facilitating the return of ...

Uncoupling mechanism and redox regulation of mitochondrial uncoupling protein 1 (UCP1) [PDF]
Brown adipose tissue (BAT) and brown in white (brite) adipose tissue, termed also beige adipose tissue, are major sites of mammalian nonshivering thermogenesis. Mitochondrial uncoupling protein 1 (UCP1), specific for these tissues, is the key factor for heat production.

Uncoupling Protein 2, but Not Uncoupling Protein 1, Is Expressed in the Female Mouse Reproductive Tract [PDF]
Uncoupling proteins (UCPs) are transporters of the inner mitochondrial membrane. Whereas UCP1 is uniquely present in brown adipose tissue where it uncouples respiration from ATP synthesis and activates respiration and heat production, UCP2 is present in numerous tissues, and its exact function remains to be clarified.

On the Mechanism of Mitochondrial Uncoupling Protein 1 Function [PDF]
Native uncoupling protein 1 (UCP 1) was purified from rat mitochondria by hydroxyapatite chromatography and identified by peptide mass mapping and tandem mass spectrometry. Native and expressed UCP 1 were reconstituted into liposomes, and proton flux through UCP 1 was shown to be fatty acid-dependent and GDP-sensitive.

Uncoupling protein-1 is not leaky
The activity of uncoupling protein-1 (UCP1) is rate-limiting for nonshivering thermogenesis and diet-induced thermogenesis. Characteristically, this activity is inhibited by GDP experimentally and presumably mainly by cytosolic ATP within brown-fat cells.
