18. The MAGE-C(2336-344) antigenic peptide is produced by the immunoproteasome and intermediate proteasome beta1i-beta5i, but not by the standard proteasome nor intermediate proteasome beta5i. PMID: 22925930
19. high risk of colon cancer was associated with LMP7-K/Q genotype and low risk with LMP7-Q/Q genotype; results suggest the presence of LMP7-K can reduce formation of immunoproteasomes and thus peptide processing, followed by reduced peptide-HLA presentation, a crucial factor in the immune response against cancer PMID: 22037870
20. CANDLE syndrome is caused by mutations in PSMB8, a gene recently reported to cause "JMP" syndrome in adults. PMID: 21953331

23. Proteasome assembly defect due to a proteasome subunit beta type 8 (PSMB8) mutation causes the autoinflammatory disorder, Nakajo-Nishimura syndrome PMID: 21852578
24. we identified two single nucleotide polymorphisms within the beta5i/LMP7-encoding gene sequences, which were in strong linkage disequilibrium, as independent genetic risk factors for type 1 diabetes development in humans PMID: 21804012

26. PSMB8 encodes a catalytic subunit of the 20S immunoproteasomes called beta5i. Immunoproteasome-mediated proteolysis generates immunogenic epitopes presented by major histocompatibility complex (MHC) class I molecules PMID: 21129723
