Immunoproteasome function
Witryna14 lut 2024 · h s is the hazard function (defined as the risk of death of patients per time unit), and h 0s (t) is the baseline-hazard function at time t of the sth stratification. 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…
