Functional Description ? help Back to Top
Source	Description
UniProt	Transcription activator, when associated with MYB75/PAP1, MYB90/PAP2 or TT2. Involved in epidermal cell fate specification. Regulates negatively stomata formation, but, in association with TTG1 and MYB0/GL1, promotes trichome formation, branching and endoreplication. Regulates also trichome cell wall maturation. Together with MYB66/WER, promotes the formation of non-hair cells in root epidermis cells in the N position. Whereas together with CPC, promotes the formation of hair cells in root epidermis cells in the H position by inhibiting non-hair cell formation. Seems also to play a role in the activation of anthocyanin biosynthesis, probably together with MYB75/PAP1. Activates the transcription of GL2. {ECO:0000269\|PubMed:11063707, ECO:0000269\|PubMed:12917293, ECO:0000269\|PubMed:12956536, ECO:0000269\|PubMed:14561633, ECO:0000269\|PubMed:14627722, ECO:0000269\|PubMed:15361138, ECO:0000269\|PubMed:15590742}.
