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.

General info

Function

Co-chaperone for HSP70 and HSC70 chaperone proteins. 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 (PubMed : 27474739, PubMed : 9873016). Has anti-apoptotic activity (PubMed : 10597216). Plays a role in the HSF1 nucleocytoplasmic transport (PubMed : 26159920).
