HSP90AA2, or Heat shock protein 90kDa alpha family class A member 2, pseudogene, is a human gene encoded by HSP90AA2P. It may also be known as: Heat shock protein HSP 90-alpha A2; Heat shock 90 kDa protein 1 alpha-like 3; Heat shock protein HSP 90-alpha A2 pseudogene; HSP90ALPHA; HSPCA; HSPCAL3; heat shock protein 90kDa alpha (cytosolic), class A member 2, pseudogene. The encoded protein has an amino acid length of 343 and a mass of 39.4 kDa. HSP90AA2 is a member of the Heat shock protein 90 family. Homologs of this gene exist in other organisms, including: Frog.
