A family of proteins found naturally in cells throughout the human body and in many other organisms. These proteins play a crucial role in cellular stress responses, helping cells cope with various stressors and maintaining their overall health and function.

Stress Response: HSP70 is produced by cells in response to stress factors such as heat, oxidative stress, infection, or inflammation. Its primary function is to protect the cell from damage that can occur under these conditions.

Protein Folding: One of its most important roles is to assist in the folding of other proteins within the cell. Proper protein folding is critical for proteins to function correctly. HSP70 helps prevent protein misfolding, which can lead to cellular dysfunction and diseases.

Cell Survival: HSP70 plays a role in promoting cell survival during stress. It helps prevent cellular damage and cell death by stabilizing proteins that may be vulnerable to stress-induced changes.
