Proteasomes are present in the cytoplasm and in the nuclei of all eukaryotic cells, however
their relative abundance within those compartments is highly variable. In the cytoplasm …

POLYPEPTIDE AND RNA COMPONENTS OF PROTEASOMES Analysis of the subunit
composition of highly purified proteasomes by two-dimensional polyacrylamide gel …

The 26 S proteolytic complex (“26 S proteasome”) is a macromolecular assembly thought to
be involved in ATP-and ubiquitin-dependent protein degradation in the cytoplasm of higher …

Proteasomes are eukaryotic ring-shaped or cylindrical particles with multicatalytic protease
activities. To clarify the involvement of proteasomes in tumorigenesis of human blood cells …

The assembly of individual proteasome subunits into catalytically active mammalian 20S
proteasomes is not well understood. Using subunit‐specific antibodies, we characterized …

Proteasomes (multicatalytic proteinase complexes), which are identical to the ubiquitous
eukaryotic 20S particles, are localized in both the cytoplasm and the nucleus, but the …

Degradation of rapidly turned over cellular proteins is commonly thought to be energy
dependent, to require tagging of protein substrates by multi-ubiquitin chains, and to involve …

Bean (Phaseolus vulgaris), an important component in the diet of people in developing
countries, has low levels of the essential amino acid, methionine. We have attempted to …

We describe the isolation and characterization of proteasomes from recently established
immortalized ovarian granulosa cell lines and their intracellular distribution during mitosis …

The eukaryotic proteasome is a barrel-shaped protease complex made up of four seven-
membered rings of which the outer and inner rings may contain up to seven different α-and β …
