Molecular insights into the unique properties of the blood-circulating proteasome.

Proteasomes are essential for protein degradation and maintaining cellular balance, yet their roles in extracellular fluids are not well understood. Our study investigates the freely circulating proteasome in blood, to uncover its unique molecular characteristics, compared to its intracellular counterparts. Using a transgenic mouse model, mass spectrometry, and biochemical tools, we show that the predominant proteasome in serum is the free uncapped 20S particle, which seems to assemble intracellularly before entering the bloodstream.
