該基因編碼mrp/nbp35 atp結合蛋白家族的一個成員。編碼的蛋白質是組裝呼吸鏈nadh脫氫酶（復合物i）所必需的，該復合物是位于線粒體內膜的低聚酶復合物。該基因突變導致線粒體復合物I缺乏選擇性剪接導致多個轉錄變體[由RefSeq提供，2014年5月]
This gene encodes a member of the Mrp/NBP35 ATP-binding proteins family. The encoded protein is required for the assembly of the respiratory chain NADH dehydrogenase (complex I), an oligomeric enzymatic complex located in the inner mitochondrial membrane. Mutations in this gene cause mitochondrial complex I deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]
