Heat stress is a condition when the environmental temperature is higher than the upper critical temperature of the animalís core body temperature. This results in the imbalance in body homeostasis of the animal. A large number of proteins are being constantly expressed in the animalís body during the time of heat stress. Amongst all those proteins, heat shock proteins are the major family of proteins which have shown a great potential to ameliorate the deleterious effects of heat stress. Hsp70 is a ubiquitously expressed protein which protects cell from heat stress by maintaining cellular machinery through proper folding of denatured proteins and preventing cellular apoptosis. Therefore it is paramount to know the mechanism of cellular protection by prevention of apoptosis during heat stress. The present review highlights the regulatory role of HSP70 on cellular machinery during heat stress.
