Functional Description ? help Back to Top
Source	Description
UniProt	Controls the expression of genes involved in anthocyanin biosynthesis. Regulates the expression of at least 3 structural genes: chalcone synthase, dihydroflavonol reductase and flavonol O(3) glucosyltransferase. C1 acts as a trans-acting factor.
