DESCRIPTION

Also known as BAG1_MOUSE, Bag1. Co-chaperone for HSP70 and HSC70 chaperone proteins (PubMed:9873016). Acts as a nucleotide-exchange factor (NEF) promoting the release of ADP from the HSP70 and HSC70 proteins thereby triggering client/substrate protein release. Nucleotide release is mediated via its binding to the nucleotide-binding domain (NBD) of HSPA8/HSC70 where as the substrate release is mediated via its binding to the substrate-binding domain (SBD) of HSPA8/HSC70. Inhibits the pro-apoptotic function of PPP1R15A, and has anti-apoptotic activity. Markedly increases the anti-cell death function of BCL2 induced by various stimuli (By similarity). Homodimer. Forms a heteromeric complex with HSP70/HSC70. Binds to the ATPase domain of HSP/HSC70 chaperones. Interacts with NR3C1. Interacts with the N-terminal region of STK19. Interacts with PPP1R15A. Interacts with BCL2 in an ATP-dependent manner. Interacts with SIAH1, HSPA8 (via NBD), HSPA1A (via NBD) and HSPA1B (via NBD) (By similarity). Interacts with SIAH2 (PubMed:11257006).
