Expression -- Description ? help Back to Top
Source Description
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}.
Functional Description ? help Back to Top
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}.

Source Description
UniProtINDUCTION: Transcriptional activation correlates with reduced histone acetylation on H3 and H4 mediated by HDA18 in N cells. Repressed by CPC in hair cells (H position). {ECO:0000269|PubMed:11910008, ECO:0000269|PubMed:16176989}.
