Regulated proteolysis in light signaling

Curr Opin Plant Biol. 2005 Oct;8(5):469-76. doi: 10.1016/j.pbi.2005.07.002.


Photoreceptors regulate many aspects of development throughout the life cycle of a plant. Recent advances have demonstrated the importance of ubiquitin-mediated proteolysis in the control of development by light. Both some of the photoreceptors themselves and, in particular, transcription factors that are involved in transducing the light signal are subject to regulated ubiquitination and subsequent degradation by the 26S proteasome.
