The incorporation of catalytic subunits β1i, β2i, and β5i into 20S core particle leads to the enhanced proteolytic activities and improved accessibility for …
Witryna1 sty 2012 · Immunoproteasomes exhibit both immune and non-immune functions (160). Besides its role in maintaining protein homeostasis and antigen presentation, the immunoproteasome plays a crucial role in ... 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…
