70-kDa Heat Shock Protein (Hsp70) is an abundant protein cofactor commonly known as a molecular chaperone. Found in most eukaryotes, Hsp genes are members of a heat-inducible multigene family. These proteins are found in most cellular compartments of eukaryotes - everything from nuclei, mitochondria, chloroplasts, to endoplasmic reticulum and cytosol.
