Human BAG2 Protein expressed in Escherichia coli (E. coli) - ABIN667379
Arndt, Daniel, Nastainczyk, Alberti, Höhfeld: BAG-2 acts as an inhibitor of the chaperone-associated ubiquitin ligase CHIP. in Molecular biology of the cell 2005
Show all 2 references for ABIN667379
Data show that BAG2 Inhibits CHIP-Mediated HSP72 (show HSPA1A Proteins) ubiquitination in aged cells.
repression of BAG2 expression or BAG2 activity by cold-sensitive pathways, as modeled in undifferentiated and differentiated cells, respectively, may be a causal factor in the accumulation of cytotoxic hyperphosphorylated tau protein.
NF-kappaB (show NFKB1 Proteins)-mediated modulation of BAG2 expression regulates the shift between the neurotrophic and neurotoxic effects of Abeta1-42.
Thus, BAG2 promotes mutant p53 (show TP53 Proteins) accumulation and gain-of-function in tumor growth, metastasis and chemoresistance.
This study showed that BAG2 (Bcl-2 (show BCL2 Proteins) associated athanogene family protein 2) and BAG5 (show BAG5 Proteins) (Bcl-2 (show BCL2 Proteins)-associated athanogene family protein 5 (show CAPS Proteins)) stabilise pathogenic ataxin3-80Q by inhibiting its ubiquitination
we measured the binding of human Hsp72 (HSPA1A (show HSPA1A Proteins)) to BAG1 (show BAG1 Proteins), BAG2, BAG3 (show BAG3 Proteins), and the unrelated NEF Hsp105 (show HSPH1 Proteins). These studies revealed a clear hierarchy of affinities: BAG3 (show BAG3 Proteins) > BAG1 (show BAG1 Proteins) > Hsp105 (show HSPH1 Proteins) >> BAG2.
this data correlate BAG2 to PINK1 (show PINK1 Proteins) for the first time, strengthening the important role of BAG2 in Parkinson disease -related neurodegeneration.
BAG2 was directly phosphorylated at serine 20 in vitro by MAPKAPK2 (show MAPKAPK2 Proteins) and MAPKAP2 is also required for phosphorylation of BAG2 in vivo.
BAG2 binds to the carboxyl terminus of Hsp70-interacting protein (show HSPBP1 Proteins) (CHIP) and provides a cochaperone-dependent regulatory mechanism for preventing unregulated ubiquitylation of misfolded proteins by CHIP
The activity of BAG-2 resembles that of the previously characterized Hsc70 (show HSPA8 Proteins) cochaperone and CHIP inhibitor HspBP1 (show HSPBP1 Proteins).
findings support the notion that BAG2 is an upstream regulator of the PINK1 (show PINK1 Proteins)/PARKIN (show PARK2 Proteins) signaling pathway.
Native Bag2-NTD crystals diffracted to 2.27 A resolution and belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 75.5, b = 84.7, c = 114.1 A
Free and Hsc70 (show HSPA8 Proteins)-bound crystal structures of Bag2-BNB show its dimeric structure, in which a flanking linker helix and loop bind to Hsc70 (show HSPA8 Proteins) to promote nucleotide exchange.
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 predicted BAG2 protein contains 211 amino acids. 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.
