Immunoproteasome vs proteasome
Did you know?
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… WitrynaAs nouns the difference between immunoproteasome and proteasome. is that immunoproteasome is (biochemistry) a proteasome assembled using alternative β …
WitrynaUsing exome analysis, we found a homozygous missense mutation (G197V) in immunoproteasome subunit, β type 8 (PSMB8), which encodes one of the β subunits induced by IFN-γ in patients from 2 consanguineous families. ... resulting in decreased proteasome function and ubiquitin-coupled protein accumulation in the patient's … 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.
