The main functional compartments of molecular chaperone Hsp60 are mitochondria and cytoplasm. Up to 30 % of Hsp60 are located in cytoplasm of cardiomyocytes. The interaction between molecular chaperone Hsp60 and proapoptotic Bax protein in the cytoplasmic fraction from normal human heart tissue has been revealed by co-immunoprecipitation in contrast to myocardium affected by dilated cardiomyopathy, where this interaction has not been observed.
