由该基因编码的蛋白质是一个亚基的烟酰胺腺嘌呤二核苷酸氧化还原酶（复杂的I）。哺乳动物复合体I位于线粒体内膜该蛋白具有NADH脱氢酶活性和氧化还原酶活性。它将电子从nadh转移到泛醌。人类基因突变与多发性先天性异常3的线性皮肤缺损和线粒体复合物i缺乏有关。[由RefSeq提供，2016年12月]
The protein encoded by this gene is a subunit of the multisubunit NADH:ubiquinone oxidoreductase (complex I). Mammalian complex I is located at the mitochondrial inner membrane. This protein has NADH dehydrogenase activity and oxidoreductase activity. It transfers electrons from NADH to ubiquinone. Mutations in the human gene are associated with linear skin defects with multiple congenital anomalies 3 and mitochondrial complex I deficiency. [provided by RefSeq, Dec 2016]
