**Background of Recombinant Human PSMD12 Protein**
The proteasome 26S subunit, non-ATPase 12 (PSMD12), also known as RPN5. is a critical component of the 26S proteasome, a large multiprotein complex responsible for targeted protein degradation in eukaryotic cells. As part of the 19S regulatory particle (RP) within the 26S proteasome, PSMD12 plays a pivotal role in the ubiquitin-proteasome system (UPS), which regulates cellular protein turnover by recognizing and degrading ubiquitin-tagged substrates. Structurally, PSMD12 contains a conserved PCI (proteasome, COP9/signalosome, eIF3) domain, facilitating its interaction with other 19S subunits to maintain proteasome integrity and function.
Recombinant human PSMD12 protein is engineered using expression systems like *E. coli* or mammalian cells, enabling studies on proteasome assembly, substrate recognition, and deubiquitination processes. Its recombinant form is vital for dissecting molecular mechanisms underlying diseases linked to UPS dysregulation, including neurodegenerative disorders (e.g., Alzheimer’s and Parkinson’s) and cancers, where proteasome inhibitors (e.g., bortezomib) are clinically utilized. Additionally, PSMD12’s role in cell cycle control, DNA repair, and stress responses highlights its potential as a therapeutic target.
Research on recombinant PSMD12 advances drug discovery, structural biology, and understanding proteostasis, offering insights into cellular quality control pathways and their pathological disruptions.
