IFN-γ-induced de novo formation of immunoproteasomes, therefore, essentially supports the rapid adjustment of the mammalian immune system. Here, we report that the molecular interplay between … flowertour.nlAn immunoproteasome is a type of proteasome that degrades ubiquitin-labeled proteins found in the cytoplasm in cells exposed to oxidative stress and proinflammatory stimuli. In general, proteasomes consist of a regulatory and a catalytic part. Immunoproteasomes are induced by interferon gamma (but also by other proinflammatory cytokines) and oxidative stress, which in the cell triggers the transcription of three catalytic subunits that do not occur in the classical proteas… flower tour
