caution:The sequence shown here is derived from an Ensembl automatic analysis pipeline and should be considered as preliminary data.,function:Implicated in immunoproteasome assembly and required for efficient antigen processing. The PA28 activator complex enhances the generation of class I binding peptides by altering the cleavage pattern of the proteasome.,induction:By interferon gamma.,similarity:Belongs to the PA28 family.,subunit:Heterodimer of PSME1 and PSME2, which forms a hexadimeric ring. PSME1 can form homoheptamers.,
