Protein degradation in signaling

Curr Opin Plant Biol. 2000 Oct;3(5):381-6. doi: 10.1016/s1369-5266(00)00100-x.


Recent studies have linked proteolysis by the ubiquitin/proteasome pathway to a variety of signaling pathways in higher plants. These links were uncovered by characterization of mutants altered in signaling or by targeted disruption of components of the proteolytic pathway. Significant advances have recently revealed connections between proteolysis and hormone responses, light perception, environmental adaptation, and floral development.
