    Specificity / Sensitivity

    PA28α (D4F12) Rabbit mAb recognizes endogenous levels of total PA28α protein. This antibody does not cross-react with either PA28β/PSME2 or PA28γ/PSME3 protein.

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human PA28α protein.

    Western Blotting

    Western Blotting

    Western blot analysis of extracts from 293T cells, either mock transfected (-) or transfected with Myc/DDK-tagged cDNA expression constructs encoding full-length human PA28α (hPA28α; +), full-length human PA28β (hPA28β; +), or full-length human PA28γ (hPA28γ; +), using PA28α (D4F12) Rabbit mAb (upper) and DYKDDDDK Tag Antibody (Binds to same epitope as Sigma's Anti-FLAG® M2 Antibody) #2368 (lower).

    Western Blotting

    Western Blotting

    Western blot analysis of extracts from various cell lines using PA28α (D4F12) Rabbit mAb.

    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).
