An 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… Witryna12 lut 2024 · A number sign (#) is used with this entry because of evidence that proteasome-associated autoinflammatory syndrome-1 (PRAAS1) is caused by homozygous mutation in the PSMB8 gene ( 177046) on chromosome 6p21.
