This protein was first observed in the chromosomes of fruit fly in response to unlethal hyperthermia, so it is also called"heat shock protein"(Hsp). Except for heat shock, the stress or heat shock proteins can also be induced by exposure to environmental stress, such as cold injury, chemicals such as alcohol, Cdand other heavy metal, amino acid analogues and
