BAG2 blocking peptide

BAG proteins compete with Hip for binding to the Hsc7/Hsp7 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 predicted BAG2 protein contains 211 amino acids. The BAG domains of BAG1, BAG2, and BAG3 interact specifically with the Hsc7 ATPase domain in vitro and in mammalian cells. All 3 proteins bind with high affinity to the ATPase domain of Hsc7 and inhibit its chaperone activity in a Hip-repressible manner. [provided by RefSeq, Jul 28]
