The PSMB5 antibody targets the proteasome subunit beta type-5 (PSMB5), a critical component of the 20S proteasome core complex responsible for protein degradation in eukaryotic cells. PSMB5. also known as β5 or LMP7. is a catalytic subunit with chymotrypsin-like activity, playing a key role in the ubiquitin-proteasome system (UPS) by cleaving peptide bonds after hydrophobic residues. This subunit is essential for maintaining cellular homeostasis, regulating processes such as cell cycle progression, apoptosis, and stress response. Dysregulation of PSMB5 is linked to various diseases, including cancer, neurodegenerative disorders, and autoimmune conditions.
In cancer research, PSMB5 is of particular interest due to its role in resistance to proteasome inhibitors like bortezomib, a therapy for multiple myeloma. Overexpression or mutations in PSMB5 can reduce drug efficacy, making it a biomarker for studying therapeutic resistance. Additionally, PSMB5 is part of the immunoproteasome, which is induced by interferon-γ and involved in antigen presentation, linking it to immune responses and autoimmune diseases.
Antibodies against PSMB5 are widely used in Western blotting, immunohistochemistry, and immunofluorescence to analyze its expression, localization, and interaction partners. These tools help elucidate proteasome dynamics in disease models and drug development. Research continues to explore PSMB5-targeting strategies to overcome treatment resistance or modulate proteasome activity in pathological conditions.
