The … Witryna20 cze 2005 · As observed previously with standard proteasomes, immunoproteasome assembly accompanied POMP degradation. Importantly, immunoproteasomes are assembled four times faster than standard proteasomes (21 min vs. 82 min half-time of assembly), raising the issue of why standard proteasomes aren't assembled faster.

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… buffolo grove beauty salonWitrynaAn essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides.
