HSP90AA1（heat shock protein 90 alpha family class A member 1），癌症关联基因，基因ID：3320，该基因编码的蛋白质是一种可诱导的分子伴侣，具有同源二聚体的功能。编码的蛋白质通过协同伴侣调节的atp酶活性有助于特定靶蛋白的正确折叠。已经发现了两个编码不同亚型的转录变体。[由RefSeq提供，2012年1月]The protein encoded by this gene is an inducible molecular chaperone that functions as a homodimer. The encoded protein aids in the proper folding of specific target proteins by use of an ATPase activity that is modulated by co-chaperones. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq， Jan 2012]。
