Abstract: Abstract: This paper discussed the classification, function, mechanism, current research progress and the application prospect of the molecular chaperone. Molecular chaperones are a serial group of proteins which are found in all living organism, helping in the process of the folding, assembly, transportation and degradation of huge biological molecule, and participating in antigen presentation, in replication, transcription and conformational decision of genetic substance. But molecular chaperones don{$39}t change themselves at all when they work. With the further development of research and the associated knowledge of molecular chaperone, there will be extensive prospects of the application in exploiting bio-products, improving species, anti-aging, diagnosing and treating disease, monitoring environment and so on.
Key words: molecular chaperone; protein folding; heat shock proteins; signal transduction; apoptosis
