Derangements in normal cellular homeostasis at the protein level can cause or be the consequence of initiation and progression of pulmonary diseases related to genotype, infection, injury, smoking, toxin exposure, or neoplasm. We discuss one of the fundamental mechanisms of protein homeostasis, the ubiquitin proteasome system (UPS), as it relates to lung disease. The UPS effects selective degradation of ubiquitinated target proteins via ubiquitin ligase activity. Important pathobiological mechanisms relating to the UPS and lung disease have been the focus of research, with inappropriate cellular proteolysis now a validated therapeutic target. We review the contributions of this system in various lung diseases, and discuss the exciting area of UPS-targeting drug development for pulmonary disease.
