Source Description
UniProtTranscription factor that binds DNA to G box 5'-CACGTG-3' and, to a lower extent, to E-box 5'-CANNTG-3' in vitro. Binds to chromatin DNA of the FT gene and promotes its expression, and thus triggers flowering in response to blue light. {ECO:0000269|PubMed:18988809, ECO:0000269|PubMed:24130508}.

Regulation -- Description ? help Back to Top
Source Description
UniProtINDUCTION: Accumulates strongly in response to blue light due to reduced preventing 26S proteasome-mediated degradation in an ADO1/ZTL and ADO2/LKP2 dependent manner, but levels decrease in the absence of blue light via 26S proteasome degradation (at protein level). {ECO:0000269|PubMed:24101505}.
