Functional Description ? help Back to Top
Source	Description
UniProt	Transcription activator, when associated with BHLH2/EGL3/MYC146 or BHLH12/MYC1. Involved in epidermal cell fate specification in roots and hypocotyl. Together with GL3 or BHLH2, promotes the formation of non-hair developing cells (atrichoblasts) et the N position in root epidermis. Regulates stomata spatial distribution in hypocotyls. Binds to the WER-binding sites (WBS) promoter regions and activates the transcription of target genes such as GL2 and of CPC. {ECO:0000269\|PubMed:10589676, ECO:0000269\|PubMed:11585796, ECO:0000269\|PubMed:14627722, ECO:0000269\|PubMed:15361138, ECO:0000269\|PubMed:15795220, ECO:0000269\|PubMed:16207757}.
