Scientific Background Selectively interacts with HSP70 and disrupts its association with co-chaperones and substrate proteins. It induces apoptosis and is cell permeable. Also, inhibits p53 binding to mitochondria by reducing its affinity for antiapoptotic proteins Bcl-2 and Bcl-XL. Looking for more information on HSP70?
