The protein encoded by HSP90AA1（heat shock protein 90 alpha family class A member 1） 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 HSP90AA1.基因ID為：3320；蛋白質ID:P07900
