Figure 1. — Protein sequence alignment of Arabidopsis R2R3 MYB subfamily 22. The R2R3 repeats of the DNA binding domain (grey) and putative transcriptional repressor motif (yellow) are highlighted. The known MPK3 phosphorylation site in MYB44 (Ser145) is indicated. The N-terminal (aa1-212) MYB44 region known to bind particularly strongly to DNA (MBSII element) is shown in bold. A conserved cysteine residue potentially involved in redox-dependent MYB activity is underlined. “.” “:” and “*” mark residues with low, moderate and high conservation.
