| Specificity / Sensitivity | PA28β Antibody detects endogenous levels of total PA28β protein. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Lys14 of human PA28β. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from MCF7, Neuro2A, PC12 and COS cells, using PA28β Antibody. IF-IC
Confocal immunofluorescent analysis of MCF-7 cells labeled with PA28β Antibody (green). Actin filaments have been labeled with Alexa Fluor® 555 phalloidin (red). |
| Background | The 20S proteasome is the major proteolytic enzyme complex involved in intracellular protein degradation. PA700, PA28, and PA200 are three major protein complexes that function as activators of the 20S proteasome. There are three evolutionarily conserved subunits of PA28: PA28α (PSME1), PA28β (PSME2), and PA28γ (PSME3) (1,2). PA28α and PA28β form a heteroheptameric complex and function by binding to the 20S complex at its opening site(s). The PA28α/β complex is present throughout the cell and participates in MHC class I antigen presentation by promoting the generation of antigenic peptides from foreign proteins (2). PA28γ exists in the form of a homoheptamer and is mainly located in the nucleus. The PA28γ complex exerts its function by binding and guiding specific nuclear target proteins to the 20S proteasome for further degradation (3,4). |
