COX18（cytochrome c oxidase assembly factor COX18），癌症关联基因，基因ID：285521，该基因编码细胞色素c氧化酶组装蛋白。编码蛋白是将膜蛋白插入线粒体内膜所必需的。它也需要细胞色素C氧化酶的组装和活性。选择性剪接导致多个转录变体[由RefSeq提供，2014年7月]This gene encodes a cytochrome c oxidase assembly protein. The encoded protein is essential for integral membrane protein insertion into the mitochondrial inner membrane. It is also required for cytochrome c oxidase assembly and activity. Alternative splicing results in multiple transcript variants. [provided by RefSeq， Jul 2014]。
