该基因编码一种线粒体金属蛋白酶蛋白，是a a a家族的一员。这个蛋白家族的成员共享一个atpase结构域，并在多种细胞过程中发挥作用，包括膜运输、细胞内运动、细胞器生物发生、蛋白质折叠和蛋白质分解。该基因突变导致常染色体隐性遗传性痉挛性截瘫7已经鉴定出两个编码不同亚型的转录变体[由RefSeq提供，2014年3月]
This gene encodes a mitochondrial metalloprotease protein that is a member of the AAA family. Members of this protein family share an ATPase domain and have roles in diverse cellular processes including membrane trafficking, intracellular motility, organelle biogenesis, protein folding, and proteolysis. Mutations in this gene cause autosomal recessive spastic paraplegia 7. Two transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Mar 2014]
