Photoactivated phytochrome induces rapid PIF3 phosphorylation prior to proteasome-mediated degradation.

Molecular cell - 4 Aug 2006

Abstract excerpt

Following light-induced nuclear translocation, specific members of the phytochrome (phy) photoreceptor family (phyA to phyE) interact with bHLH transcription factors, such as PIF3, and induce changes in target-gene expression. The biochemical mechanism comprising signal transfer from phy to PIF3 has remained undefined but results in rapid degradation of PIF3. We provide evidence that photoactivation of phy...
