The 20S proteasome and the 26S proteasome are major components of the cytosolic and nuclear proteasomal proteolytic systems. Since proteins are known to be highly susceptible targets for reactive oxygen species, the effect of H(2)O(2) treatment of K562 human hematopoietic

In Huntington's disease (HD), as in the rest of CAG triplet-repeat disorders, the expanded polyglutamine (polyQ)-containing proteins form intraneuronal fibrillar aggregates that are gathered into inclusion bodies (IBs). Since IBs contain ubiquitin and proteasome subunits, it was proposed that inhibition

The ubiquitin/proteasome pathway mediates the degradation of many short-lived proteins that are critically involved in the regulation of cell proliferation and cell death, including the tumor suppressor protein p53. Accumulation of p53 and induction of apoptosis in RAW 264.7 macrophages

The 20S proteasome has been shown to be largely responsible for the degradation of oxidatively modified proteins in the cytoplasm. Nuclear proteins are also subject to oxidation, and the nucleus of mammalian cells contains proteasome. In human beings, tumor cells

Protein homeostasis is an emerging component of schizophrenia (SZ) pathophysiology. Proteomic alterations in SZ are well-documented and changes in transcript expression are frequently not associated with changes in protein expression in SZ brain. The underlying mechanism driving these changes remains
