Expression -- Description ? help Back to Top
Source	Description
Uniprot	DEVELOPMENTAL STAGE: Expressed in leaves from the third leaf to rosette leaves from six-week old plants. Expression follows a development-dependent gradient in successive leaves. {ECO:0000269\|PubMed:9678577}.
Uniprot	TISSUE SPECIFICITY: Expressed in roots, stems and flowers. Expressed in dry seeds (PubMed:9678577). Expressed in root vasculature, root tips and lateral root (PubMed:17675404). {ECO:0000269\|PubMed:17675404, ECO:0000269\|PubMed:9678577}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor involved in auxin response. Functions in auxin signal transduction and modulates lateral root growth. Interacts with ARF response factors to promote auxin-responsive gene expression (PubMed:17675404). In response to auxin, binds sequence-specific motifs in the promoter of the auxin-responsive gene IAA19, and activates IAA19 transcription. The IAA19 transcription activation by MYB77 is enhanced by direct interaction between MYB77 and PYL8 (PubMed:24894996). {ECO:0000269\|PubMed:17675404, ECO:0000269\|PubMed:24894996}.

Regulation -- Description ? help Back to Top
Source	Description
UniProt	INDUCTION: Induced by auxin (PubMed:17675404). Down-regulated by potassium deprivation (PubMed:15173595). {ECO:0000269\|PubMed:15173595, ECO:0000269\|PubMed:17675404}.
