What Roles Does the UPS Play in Cellular Functions?
The UPS is involved in numerous cellular processes, including: - Cell Cycle Regulation: It controls the degradation of cyclins and other cell cycle regulators. - Signal Transduction: The degradation of signaling proteins ensures proper cellular responses. - Apoptosis: UPS regulates pro-apoptotic and anti-apoptotic proteins, influencing cell death. - Stress Response: It helps in the removal of proteins damaged by oxidative stress or other cellular insults.
