Heat Shock 70kDa Protein 7 (HSPA7)

The 70 kilodalton heat shock proteins (Hsp70s) are a family of ubiquitously expressed heat shock proteins. Proteins with similar structure exist in virtually all living organisms. The Hsp70s are an important part of the cell's machinery for protein folding, and help to protect cells from stress.Members of the Hsp70 family are strongly upregulated by heat stress and toxic chemicals, particularly heavy metals such as arsenic, cadmium, copper, mercury, etc. Hsp70 was originally discovered by FM Ritossa in the 1960s when a lab worker accidentally boosted the incubation temperature of Drosophila (fruit flies).

Heat shock 70kDa protein 7 (HSP70B) also known as HSPA7 is a human gene. The protein encoded by this gene is a member of the Hsp70 family of heat shock proteins.
