The tobacco Myb1 protein. (A) The
deduced amino acid sequence of the Myb1 protein. The underlined
sequences were used to design degenerate primers for the PCR
amplification of the conserved regions of myb genes. The
conserved redox sensitive cysteine residue at position 53 is indicated
in boldface. (B) Schematic comparison of structural features
between Myb1 and the mouse c-Myb. R, tryptophan repeat; Cys, conserved
redox sensitive cysteine (Cys-53 in Myb1 and Cys-130 in c-Myb); P,
phosphorylation sites; NLS, nuclear localization sequences; LZ, leucine
zipper; aa, amino acid residues.
