Rabbit anti-Human UCP3 Polyclonal Antibody

Uniprot Id

P55916

Target Species

Human

Target Name

UCP3

Target Full Name

Putative mitochondrial transporter UCP3

Target Function

UCP are mitochondrial transporter proteins that create proton leaks across the inner mitochondrial membrane, thus uncoupling oxidative phosphorylation. As a result, energy is dissipated in the form of heat. May play a role in the modulation of tissue respiratory control. Participates in thermogenesis and energy balance.

Target Involvement

Obesity (OBESITY)

Target Subcellular Location

Mitochondrion inner membrane; Multi-pass membrane protein.

Target Protein Families

Mitochondrial carrier (TC 2.A.29) family

Target Tissue Specificity

Only in skeletal muscle and heart. Is more expressed in glycolytic than in oxidative skeletal muscles.

Target Synonyms

UCP3; SLC25A9; Mitochondrial uncoupling protein 3; UCP 3; Solute carrier family 25 member 9

Target Background

Mitochondrial uncoupling proteins (UCP) are members of the larger family of mitochondrial anion carrier proteins (MACP). UCPs separate oxidative phosphorylation from ATP synthesis with energy dissipated as heat, also referred to as the mitochondrial proton leak. UCPs facilitate the transfer of anions from the inner to the outer mitochondrial membrane and the return transfer of protons from the outer to the inner mitochondrial membrane. They also reduce the mitochondrial membrane potential in mammalian cells. The different UCPs have tissue-specific expression; this gene is primarily expressed in skeletal muscle. This gene's protein product is postulated to protect mitochondria against lipid-induced oxidative stress. Expression levels of this gene increase when fatty acid supplies to mitochondria exceed their oxidation capacity and the protein enables the export of fatty acids from mitochondria. UCPs contain the three solcar protein domains typically found in MACPs. Two splice variants have been found for this gene.
