该基因编码线粒体伴侣蛋白，是热休克蛋白90（hsp90）家族的成员。编码蛋白具有atp酶活性，与肿瘤坏死因子Ⅰ型相互作用，可能在调节细胞应激反应中发挥作用。交替剪接导致多个转录变体。[由RefSeq提供，2013年1月]
This gene encodes a mitochondrial chaperone protein that is member of the heat shock protein 90 (HSP90) family. The encoded protein has ATPase activity and interacts with tumor necrosis factor type I. This protein may function in regulating cellular stress responses. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jan 2013]
