Das Immunoproteasom: nicht nur eine Antigen-Prozessierungsmaschine
摘要
The immunoproteasome is a specific proteasome isoform constitutively expressed in hematopoetic cells and after interferon stimulation in none-immune cells. Its function has been predominantly correlated with antigen processing and MHC class I antigen presentation. However, in recent years it became increasingly clear that immunoproteasomes exert crucial functions in the maintenance of protein homeostasis under pro-inflammatory conditions.
