Heat shock proteins (HSPs), also called stress proteins, are a group of proteins highly conserved in all cells, which are induced when a cell undergoes various types of environmental stresses like heat, cold and oxygen deprivation. Lately it was found they were also present in cells under normal conditions. The 70kDa heat shock proteins (Hsp70s) were the most impotant family in the heat shock proteins. They work as molecular chaperones in eukaryote being involved in various cellular function,such as ...
