**Background of PSME3 Antibody**
PSME3 (Proteasome Activator Subunit 3), also known as PA28γ or REGγ, is a member of the 11S proteasome regulatory complex family, which plays a critical role in modulating the 20S proteasome's activity. Unlike other PA28 subunits (α and β), PSME3 forms a homoheptameric structure and is predominantly localized in the nucleus. It facilitates the degradation of specific proteins, including cell cycle regulators (e.g., p21) and oncogenic factors, via the ubiquitin-independent proteasome pathway. PSME3 is implicated in diverse cellular processes, such as cell proliferation, apoptosis, and DNA repair, and its dysregulation has been linked to cancers, neurodegenerative disorders, and autoimmune diseases.
Antibodies targeting PSME3 are essential tools for studying its expression, localization, and functional roles. They are widely used in techniques like Western blotting, immunohistochemistry (IHC), and immunofluorescence (IF) to investigate PSME3's involvement in disease mechanisms or its interaction with viral proteins (e.g., hepatitis C virus core protein). Additionally, PSME3 antibodies aid in exploring its potential as a therapeutic target, given its association with tumor progression and chemoresistance. Validated antibodies ensure specificity for distinguishing PSME3 from homologous subunits, supporting both basic research and clinical applications.
