Protein Degradation: Homeostasis, Stress, and Therapy
Received Date: Nov 03, 2025 / Published Date: Dec 01, 2025
Abstract
Protein degradation pathways, including the ubiquitin-proteasome system (UPS) and autophagy, are fundamental for cellular health and disease. This review explores their intricate mechanisms, from general degradation to specialized processes like mitophagy and ER-associated degradation (ERAD). Cellular stress activates autophagy, while E3 ligases like CRLs regulate cell cycle control. Targeted protein degradation (TPD) offers therapeutic opportunities, particularly in neurodegenerative diseases and cancer. The UPS also plays a critical role in inflammatory signaling. Selective autophagy mechanisms ensure precise removal of cellular targets.
