Functional Description ? help Back to Top
Source Description
UniProtTranscriptional activator involved in cell elongation. Regulates the expression of a subset of genes involved in cell expansion by binding to the G-box motif. Binds to chromatin DNA of the FT gene and promotes its expression, and thus triggers flowering in response to blue light (PubMed:24130508). {ECO:0000269|PubMed:23161888, ECO:0000269|PubMed:24130508}.
