Anti-UCP-3 antibody is suitable for use in immunohistochemistry (formalin-fixed, paraffin-embedded sections at 1:3,000 dilution, using protease-digested sections of human and mouse skeletal muscle). The antibody may also be used in immunoblot (approx. 34 kDa, additional weak bands may be detected in some preparations of brown adipose tissue extracts) and western blot (at 1:1,000 dilution, extract of E. coli expressing UCP3).
Anti-Uncoupling Protein 3 (UCP3) is developed in rabbit using a synthetic peptide corresponding to amino acid residues 254-267 of human UCP3, with N-terminal lysine added, conjugated to keyhole limpet hemocyanin (KLH). The uncoupling proteins (UCPs) are mitochondrial inner membrane proteins which comprises UCP1, 2, 3, 4 and 5. UCP3 displays two forms, a long mature, UCP3L and a short, UCP3S form. UCP3 is preferentially expressed in skeletal muscle and in brown adipose tissue (BAT).
The uncoupling proteins (UCPs) are considered as transporters functioning as enzymatic uncouplers of oxidative phosphorylation. They are capable of returning protons pumped by the respiratory chain to the mitochondrial matrix. UCP3 is an active proton transporter, regulated by CoQ (ubiquinone), fatty acids or nucleotides.
