ab92309 was shown to recognize BAG3 in wild-type cells as signal was lost at the expected MW in BAG3 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and BAG3 knockout samples were subjected to SDS-PAGE. ab92309 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1 μg/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

The Bcl-2-associated athanogene 3 commonly known as Bag3 is a protein with a molecular weight of approximately 74 kDa. It plays an important role in apoptosis regulation and stress responses by interacting with heat shock proteins. Bag3 is expressed in various tissues including the heart skeletal muscles and certain types of neurons. It functions mechanically by binding to chaperones like Hsp70 modulating their activity and helping in protein folding and degradation processes.
Biological function summary

Bag3 contributes to cell survival by assisting in protein homeostasis and mitigating stress-related cellular damage. It acts as a co-chaperone and forms part of complexes with Hsp70 HspB8 and CHIP among others. These interactions enhance the cellular capacity to handle misfolded proteins preventing the aggregation that could lead to cell toxicity. In muscle cells Bag3 plays a role in maintaining structural integrity by participating in the assembly of myofibrils critical for muscle function.

Pathways

The protein is involved in autophagy and apoptosis regulation. It actively participates in the ubiquitin-proteasome system and chaperone-mediated autophagy collaborating closely with proteins like HspB8 and Hsp70. The integration of Bag3 within these pathways highlights its involvement in removing damaged proteins and preserving cellular function during stress conditions. Additionally Bag3 contributes to the regulation of the NF-kB pathway which is involved in the immune response and inflammation.

Mutations or dysregulation of Bag3 associate with conditions such as myopathy and certain cancers. In myopathy aberrations in Bag3 affect muscle resilience and repair leading to structural muscle defects. In cancer Bag3's role in inhibiting apoptosis promotes tumor cell survival making it a target for therapeutic interventions. The protein has connections with p53 in cancer contexts where it influences cell death and survival decisions. Understanding Bag3's interactions and functions in these diseases opens new opportunities for developing treatments targeting these pathways.

Target data

Co-chaperone and adapter protein that connects different classes of molecular chaperones including heat shock proteins 70 (HSP70s), e.g. HSPA1A/HSP70 or HSPA8/HSC70, and small heat shock proteins (sHSPs), e.g. HSPB8 (PubMed : 27884606, PubMed : 30559338). Acts as a nucleotide-exchange factor (NEF) promoting the release of ADP from HSP70s, thereby triggering client protein release (PubMed : 27884606, PubMed : 30559338). Nucleotide release is mediated via BAG3 binding to the nucleotide-binding domain (NBD) of HSP70s, whereas client release is mediated via binding to the substrate-binding domain (SBD) (PubMed : 27474739, PubMed : 9873016). Has anti-apoptotic activity (PubMed : 10597216). Plays a role in the HSF1 nucleocytoplasmic transport (PubMed : 26159920).
