In molecular biology BAG domains are protein domains found in proteins which are modulators of chaperone activity they bind to HSP70/HSC70 proteins and promote substrate release. The proteins have anti-apoptotic activity and increase the anti-cell death function of BCL-2 induced by various stimuli. BAG-1 binds to the serine/threonine kinase Raf-1 or Hsc70/Hsp70 in a mutually exclusive interaction. BAG-1 promotes cell growth by binding to and stimulating Raf-1 activity.
