Proteasome activity or expression is not altered by activation of the heat shock transcription factor Hsf1 in cultured fibroblasts or myoblasts

Heat shock proteins (Hsps) with chaperoning function work together with the ubiquitin-proteasome pathway to prevent the accumulation of misfolded, potentially toxic proteins, as well as to control catabolism of the bulk of cytoplasmic, cellular protein. There is evidence for the involvement of both...
