Heat shock proteins (HSPs), also called stress proteins, are a group of proteins that are present in all cells in all life forms

they act like ‘chaperones,’ making sure that the cell’s proteins are in the right shape and in the right place at the right time. For example, HSPs help new or distorted proteins fold into shape, which is essential for their function. They also shuttle proteins from one compartment to another inside the cell, and transport old proteins to ‘garbage disposals’ inside the cell. HSPs are also believed to play a role in the presentation of pieces of proteins (or peptides) on the cell surface to help the immune system recognize diseased cells.
