This results in an increase in the amount of damaged protein within the body.

This process is essential for cells to destroy misfolded and damaged proteins.

This process is essential as it is the major pathway for the degradation of damaged proteins that have passed through the Golgi.

Ubiquitins are small proteins that help to destroy unneeded or damaged proteins.

An unneeded or damaged protein is often labeled for degradation by addition of ubiquitin.

The stress of misfolded and damaged proteins influences neuronal function and lifespan at the level of the organism.

The main function of the proteasome is to degrade unneeded or damaged proteins by proteolysis, a chemical reaction that breaks peptide bonds.

Between these two effects, it is likely that cells with aggregated α-synuclein will become less able to handle damaged or misfolded proteins.

The main function of autophagy in tumor suppression is its ability to remove damaged proteins and organelles thus limiting any cell growth instability.

The body requires amino acids to produce new proteins (protein retention) and to replace damaged proteins (maintenance).
