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.[provided by RefSeq, Nov 2008]
[中文简述(自动翻译):]  线粒体解偶联蛋白(UCP)是大家庭的线粒体阴离子载体蛋白(MACP)的成员。从ATP合成与作为热量耗散能量解偶联蛋白分离氧化磷酸化,也被称为线粒体质子泄漏。解偶联蛋白促进阴离子从内转移至线粒体外膜以及从外质子的返回转移到线粒体内膜。它们还降低在哺乳动物细胞中的线粒体膜电位。不同的解偶联蛋白具有组织特异性表达;该基因是在骨骼肌主要表达。此基因的蛋白产物是假设以防止脂质诱导的氧化应激线粒体。这种基因提高表达水平时,脂肪酸用品线粒体超过其氧化能力和蛋白质能使脂肪酸从线粒体的出口。解偶联蛋白含有典型的MACPs发现三个solcar蛋白结构域。两个剪接变异体已发现了这种基因。[由RefSeq的,2008年11月提供]
