**Background of PSMA2 Recombinant Protein**
Proteasome 20S Subunit Alpha 2 (PSMA2), also known as the 20S proteasome α2 subunit, is a critical component of the 20S core particle of the ubiquitin-proteasome system (UPS). This system plays a central role in intracellular protein degradation, regulating essential cellular processes such as cell cycle progression, apoptosis, and stress response. The 20S proteasome, a multi-subunit complex, consists of α and β subunits arranged into four stacked rings (α7β7β7α7). PSMA2. as part of the α-ring, contributes to the structural stability of the proteasome and facilitates substrate recognition and entry.
Recombinant PSMA2 protein is engineered using biotechnological methods, typically expressed in *E. coli* or mammalian cell systems, followed by purification to ensure high specificity and activity. Its recombinant form retains the functional properties of the native protein, enabling researchers to study proteasome assembly, substrate interactions, and regulatory mechanisms in vitro.
PSMA2 has garnered attention in biomedical research due to its association with diseases linked to proteasome dysfunction, including cancer, neurodegenerative disorders (e.g., Alzheimer’s and Parkinson’s), and autoimmune conditions. Overexpression or mutations in PSMA2 may alter proteasome activity, leading to abnormal protein accumulation or uncontrolled proteolysis. Recombinant PSMA2 serves as a vital tool for drug discovery, particularly in screening inhibitors or activators targeting the proteasome for therapeutic applications.
Additionally, studies leveraging recombinant PSMA2 contribute to understanding resistance mechanisms in cancer therapies, such as proteasome inhibitor-based treatments (e.g., bortezomib). By elucidating PSMA2’s structural and functional roles, researchers aim to develop targeted strategies to modulate proteasome activity, offering potential avenues for treating proteostasis-related diseases.
