Hsp70 is a type of heat shock protein that helps protect cells from stress. It does this by binding to damaged proteins and helping to break them down. Hsp70 also helps prevent the formation of new damaging proteins.
Heat shock proteins are a family of proteins that are induced by stressful conditions, such as high temperatures. Hsp70 is one member of this family. Other members include Hsp90 and Hsc70.
Hsp70 is found in all organisms, from bacteria to humans. In humans, it is encoded by the HSP70 gene. The protein made by this gene is found in many tissues, including the liver, heart, muscles, and pancreas.
Hsp70 plays an important role in protecting cells from stress. When a cell is exposed to stress, hsp70 binds to damaged proteins and helps break them down. This prevents the formation of new damaging proteins.
In addition to its protective function, hsp70 also plays a role in immunity. When viruses or other foreign invaders enter the body, hsp70 binds to their surface proteins and prevents them from infecting cells. This process is known as antigen presentation.
