Do transcription factors bind to the promoter

WebProtein HY5 is considered to be a key regulator for induction of anthocyanin biosynthesis. The MYB10 genes physically interact with HY5 to positively regulate anthocyanin biosynthesis in Arabidopsis, apple, and pear by binding to G-box motifs. However, how these transcription factors are regulated by sunlight remains unclear in 'Yunhongli No. 1'. WebSome transcription factors bind to a DNA promoter sequence near the transcription start site and help form the transcription initiation complex. Other transcription factors bind to regulatory ...
