这个基因编码一个伴侣蛋白家族的成员。编码的线粒体蛋白可能在先天免疫系统中起信号分子的作用这种蛋白质对于线粒体中新导入的蛋白质的折叠和组装是必不可少的该基因与一个相关的家族成员相邻，两个基因之间的区域起双向启动子的作用有几个假基因与这个基因有关。两个编码相同蛋白质的转录变体已经被鉴定为该基因与此基因相关的突变导致常染色体隐性遗传性痉挛性截瘫13。[由RefSeq提供，2010年6月]
This gene encodes a member of the chaperonin family. The encoded mitochondrial protein may function as a signaling molecule in the innate immune system. This protein is essential for the folding and assembly of newly imported proteins in the mitochondria. This gene is adjacent to a related family member and the region between the 2 genes functions as a bidirectional promoter. Several pseudogenes have been associated with this gene. Two transcript variants encoding the same protein have been identified for this gene. Mutations associated with this gene cause autosomal recessive spastic paraplegia 13.
