BAG proteins compete with Hip for binding to the Hsc70/Hsp70 ATPase domain and promote substrate release. All the BAG proteins have an approximately 45-amino acid BAG domain near the C terminus but differ markedly in their N-terminal regions. The protein encoded by this gene contains a WW domain in the N-terminal region and a BAG domain in the C-terminal region. The BAG domains of BAG1, BAG2, and BAG3 interact specifically with the Hsc70 ATPase domain in vitro and in mammalian cells. All 3 proteins bind with high affinity to the ATPase domain of Hsc70 and inhibit its chaperone activity in a Hip-repressible manner.

Interaction
Binds to the ATPase domain of HSP70/HSC70 chaperones (PubMed:9873016). Interacts with BCL2 (PubMed:10597216). Interacts with phospholipase C-gamma proteins (PubMed:10980614). Interacts with DNAJB6 (PubMed:22366786). Interacts (via BAG domain) with HSF1; this interaction occurs in normal and heat-shocked cells promoting HSF1 nucleocytoplasmic shuttling (PubMed:26159920). Interacts with HSPA8 (via NBD) (PubMed:27474739, PubMed:24318877). Interacts with HSPA1A (via NBD) and HSPA1B (via NBD) (PubMed:24318877). Interacts (via WW domain 1) with SYNPO2 (via PPPY motif) (PubMed:23434281). Interacts with HSPB8 (PubMed:28144995).
