Source Description
TAIREncodes a member of the SPL (squamosa-promoter binding protein-like)gene family, a novel gene family encoding DNA binding proteins and putative transcription factors. Contains the SBP-box, which encodes the SBP-domain, required and sufficient for interaction with DNA. It is involved in regulation of flowering and vegetative phase change. Its temporal expression is regulated by the microRNA miR156. The target site for the microRNA is in the 3'UTR.
UniProtTrans-acting factor that binds specifically to the consensus nucleotide sequence 5'-TNCGTACAA-3' of AP1 promoter. Promotes both vegetative phase change and flowering. {ECO:0000269|PubMed:10524240, ECO:0000269|PubMed:16914499}.
Function -- GeneRIF ? help Back to Top
  1. Data indicate that although miR172 and miR156 play distinct roles in the timing of developmental phase transitions, there is a signaling crosstalk mediated by the SPL3/4/5 genes.
