该基因编码铁铁蛋白家族的成员。编码蛋白是线粒体内膜的跨膜蛋白，是线粒体呼吸稳态和红细胞生成所必需的。该基因突变与线粒体病和大细胞性贫血有关另外，在这个基因中发现了剪接的转录变体。[由RefSeq提供，2014年1月]
This gene encodes a member of the sideroflexin family. The encoded protein is a transmembrane protein of the inner mitochondrial membrane, and is required for mitochondrial respiratory homeostasis and erythropoiesis. Mutations in this gene are associated with mitochondriopathy and macrocytic anemia. Alternatively spliced transcript variants have been found in this gene. [provided by RefSeq, Jan 2014]
