UCP3

UCP3

A gene on chromosome 11q13.4 that encodes one of the mitochondrial uncoupling proteins (UCP), which belong to the family of mitochondrial anion carrier proteins (MACPs). UCPs separate oxidative phosphorylation from ATP synthesis (the so-called mitochondrial proton leak); facilitate the transfer of anions from the inner to the outer mitochondrial membrane, and protons from the outer to the inner mitochondrial membrane; and reduce the mitochondrial membrane potential in mammalian cells. UCP3 is expressed primarily in skeletal muscle, and thought to protect mitochondria against lipid-induced oxidative stress.

Independent of nutritional ketosis, increased dietary fat intake increases expression of UCP2 and UCP3 in muscle [142], and fatty acids facilitate uncoupling through UCP2 [143, 144], UCP3 [94, 143, 144], and ANT [145].

Craig Warden will look for the effects of fructose on the activity of two genes, UCP2 and UCP3. Both genes are thought to control how much energy we expend, and thus, how many calories we burn.
Briefly, UCPs are composed of five isoforms in mammals, including UCP1, UCP2, UCP3, UCP4, and UCP5 [5].
H3R knockout mice exhibit an obese phenotype, suggesting that H3R regulates insulin resistance and leptin release, as well as a decrease in homeostatic energy, the cellular process for coordinating homeostatic regulation of food intake (energy inflow) and energy expenditure (energy outflow), as associated with the UCP1 and UCP3 genes [17].
(2009), indicated that UCPs are under direct regulation by the VD/VDR signaling, furthermore, showed that VDR overexpression in the adipose tissue led to the suppression of UCP1, UCP2, and UCP3 (Wong et al., 2011).
To validate the results of the gene chips, RT-PCR was carried out for three upregulated genes (SREBF1, DUSP1, and PLAGL1) and seven downregulated genes (FKBP5, ZBTB16, PPP1R3C, CDC14A, GLUL1, PDK4, and UCP3).
