The function of the immunoproteasome is primarily to specifically cleave proteins into shorter peptides, which can then be displayed on the cell surface together with the MHC I complex. The MHC I complex with bound peptide is then recognized primarily by cytotoxic T cells. In order to expose a peptide on the cell surface, the ubiquitin-labeled protein, specifically cleaved into peptides by immunoproteasome, must first be transferred to the endoplasmic reticulum using TA… WitrynaThe immunoproteasome and thymoproteasome: functions, evolution and human disease Nat Immunol. 2024 Sep;19(9):923-931. doi: 10.1038/s41590-018-0186-z. ... the immunoproteasome and the thymoproteasome.
