Polyclonal Rabbit Affinity Purified B
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 evolutionary conserved subunits of PA28; PA28 (PSME1), PA28 (PSME2) and PA28 (PSME3) (1,2). PA28 and PA28 form a heteroheptameric complex and function by binding to the 20S complex at its opening site(s). The PA28 / complex is present throughout the cell and participates in MHC class I antigen presentation by promoting the generation of antigenic peptide from foreign proteins (2). PA28 exists in the form of a homoheptamer and is mainly located in the nucleus. PA28 complex exerts its function by binding and guiding specific nuclear target proteins to the 20S proteasome for further degradation (3,4).
