Abstract:The autophagy-lysosomal pathway (ALP) and the ubiquitin-proteasome system (UPS) are the two major intracellular proteolytic systems that mediate protein turnover in eukaryotes. Although a crosstalk exists between these two systems, it is still unclear how UPS and ALP interact in vivo. Here, we have investigated how impaired function of the proteasome-associated deubiquitinating enzyme (DUB) Uchl5/UBH-4, a regulator of proteasome activity, affects autophagy in human cells and in various tissues in a multicellul… Show more
