Source Description
UniprotDEVELOPMENTAL STAGE: First expressed in leaf primordia. Later confined to developing trichome cells where it persists at high levels throughout all stages of trichome development. {ECO:0000269|PubMed:11437443, ECO:0000269|PubMed:15728674}.
UniprotTISSUE SPECIFICITY: Expressed in roots, seed coats, leaves, stems and flowers. Detected specifically in trichomes, and in the cell division and differentiation zone of the root. {ECO:0000269|PubMed:11437443}.
UniprotTISSUE SPECIFICITY: Restricted to roots and hypocotyl. Specifically expressed in root non-hair developing cells (atrichoblasts) at the N position. Also present in lateral root cap cells. In hypocotyls, expressed within files of epidermal cells located outside a single cortical cell equivalent to roots N cells (at protein level). {ECO:0000269|PubMed:10589676, ECO:0000269|PubMed:14627722, ECO:0000269|PubMed:16207757}.

Source Description
UniProtTranscription 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}.
UniProtTranscription activator, when associated with BHLH2/EGL3/MYC146 or BHLH12/MYC1. Regulates the epidermal cell fate specification. Mediates the formation of columellae and accumulation of mucilages on seed coats. Controls the elongation of epidermal cells positively in roots but negatively in stems, leading to the promotion of primary roots elongation and repression of leaves and stems elongation, respectively. Ovoids ectopic root-hair formation, probably by inducing GL2 in roots. Controls trichome initiation and branching. {ECO:0000269|PubMed:11437443, ECO:0000269|PubMed:15361138, ECO:0000269|PubMed:15668208, ECO:0000269|PubMed:15728674}.
