Molecular alterations in proteasomes of rat liver during aging result in altered proteolytic activities
Aging induces alterations of tissue protein homoeostasis. To investigate one of the major systems catalysing intracellular protein degradation we have purified 20S proteasomes from rat liver of young (2 months...

The base of the proteasome regulatory particle exhibits chaperone-like activity
Protein substrates of the proteasome must apparently be unfolded and translocated through a narrow channel to gain access to the proteolytic active sites of the enzyme. Protein folding in vivo is mediated by mole...
