NCBI Protein Information
myb domain protein 23
NCBI Summary
Encodes a MYB gene that, when overexpressed ectopically, can induce ectopic trichome formation. It is a member of subgroup 15, together with WER and GL1. Members of this subgroup share a conserved motif of 19 amino acids in the putative transcription activation domain at the C-terminal end. The gene is expressed in leaves, stems, flowers, seeds and roots and quite strongly in trichomes. There is partial functional redundancy between ATMYB23 and GL1. The two proteins are functionally equivalent with respect to the regulation of trichome initiation but not with respect to trichome branching - which is controlled by MYB23 and not GL1.

UniProt Comments
Transcription 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.
