NCBI Protein Information
Transducin/WD40 repeat-like superfamily protein
NCBI Summary
Required for the accumulation of purple anthocyanins in leaves and stems. Involved in trichome and root hair development. Controls epidermal cell fate specification. Affects dihydroflavonol 4-reductase gene expression. It is thought that a ternary complex composed of TT2, TT8 and TTG1 is necessary for correct expression of BAN in seed endothelium. Based on clonal analysis and other methonds TTG1 has been shown to act non-cell autonomously and to move via plasmodesmata between cells.Localization and levels of TTG1 affect patterning of leaf trichomes. Auxin and ethylene responsiveness of TTG1 transcription is lost in myb12 mutants.

UniProt Comments
May regulate MYC transcription factors. Involved in epidermal cell fate specification such as trichome and root hair development, seed mucilage production, and anthocyanin biosynthesis by acting at the dihydroflavonol-4-reductase (DFR) step. Together with GL1 and GL3, promotes trichome formation. Activates the transcription of GL2.
