HY5: a transcription factor integrating environmental and endogenous signals in plant development and acclimation.
This review synthesizes current understanding of the multilayered regulatory networks controlling HY5, ranging from constitutive photomorphogenic 1/suppressor of phytochrome A (COP1/SPA)-mediated ubiquitin-dependent degradation, transcriptional regulation by upstream factors, and extensive post-translational modificati...
