The Trihelix transcription factor family has raised great concerns only in recent years.It was named after its conserved DNA binding domain containing three tandem helix(helix-loop-helix-loop-helix),which could bind specifically with GT element,a light-responsive DNA element.So,this family is also known as GT factors.At the early stage of study,the knowledge of this family was only confined to their functions in regulation of light-responsive genes.However,recent researches indicated that Trihelix family al...
