Summary
Protein damage contributes to aging and disease. This review highlights the proteasomal system
Area of Science:
- Cellular Biology
- Biochemistry
- Pathology
Background:
- Protein damage from radicals is implicated in aging and diseases.
- Intracellular proteolytic systems, including the proteasome, degrade damaged proteins.
- Proteasome function is crucial for maintaining protein homeostasis, especially in the nervous system.
Purpose of the Study:
- To review current knowledge on protein damage.
- To elucidate the proteasome's role in degrading damaged proteins.
- To discuss proteasome regulation and its impact on neurodegenerative diseases.
Main Methods:
- Literature review of studies on protein damage and proteasome function.
- Analysis of proteasome regulation under oxidative stress, aging, and pathology.
- Focus on the proteasome's role in neurodegenerative disease pathogenesis.
Main Results:
- The proteasome is a key player in degrading oxidized, aggregated, and misfolded proteins.
- Proteasome activity is dynamically regulated and alters with age.
- Dysfunctional proteasomes are linked to neurodegenerative disease onset.
Conclusions:
- Understanding proteasome function and regulation is vital for addressing protein damage-related diseases.
- The proteasome's role in neuronal protein homeostasis and neurodegeneration requires further investigation.

01:13The Proteasome
Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3 (ubiquitin...

01:17The Proteasome Structure
The ubiquitin-proteasome pathway is a well-known mechanism utilized by eukaryotic cells to remove cytoplasmic proteins that are misfolded, damaged, or no longer needed. In this pathway, the protein that needs to be eliminated undergoes a process called ubiquitination, where a chain of ubiquitin molecules is attached to the 48th lysine residue of the target protein. This ubiquitin modification helps the proteasome distinguish between a target protein and a healthy protein.

01:20Radical Autoxidation
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...
01:25Bioactivation and Tissue Toxicity
Bioactivation is a metabolic process that transforms less reactive substances into highly reactive metabolites, initiating tissue toxicity. This transformation can lead to various toxic effects, including carcinogenesis and teratogenesis. Reactive metabolites are classified into two main types: electrophiles and free radicals.Electrophiles are electron-deficient species and are produced primarily by the enzyme cytochrome P-450 during the metabolism of compounds containing carbon, nitrogen, or...
