Functional Description ? help Back to Top
Source Description
TAIREncodes CIB5 (cryptochrome-interacting basic-helix-loop-helix). Related to CIB1 (AT4G34530). CIB5 interacts with CRY2 and forms heterodimer with CIB1 in vitro. Regulates flowering time redundantly with CIB1.
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}.
