A new study has linked Heat Shock Protein 90 (HSP90) to the speed of change in the genome. The HSP90 protein is a highly specialized growth regulator:
HSP90 belongs to a class of proteins called chaperones, which help other proteins in the cell fold properly, prevent protein clumping, and escort improperly made proteins to be recycled. These vital functions become even more important when a cell is stressed by heat, cold, toxins or other hardships that affect protein folding.
Hsp90 is particularly interesting because it is specialized to chaperone proteins that are key regulators of growth and development.
So, it’s like a built in disk defragmentation program. It sounds like something that a good programmer would design into the program.
