How Cells Remove Unneeded Proteins

Cells remove unneeded proteins through regulated protein degradation. This process helps control which proteins stay active and which proteins are broken down.

Protein degradation is not random. The cell uses signals to mark proteins for removal at the right time. This regulation lets the cell re...

Cells need to regulate their levels of intracellular proteins according to the alterations in their state, such as environmental stimuli, or other metabolic or developmental changes. 

This regulation or control of protein concentrations inside a cell depends on their rate of synthesis as well as their degradation. 

In eukaryotes, i...
