Alignment of the deduced PwTUA1 protein sequence (EU268195) with other plant TUA1s. Amino acid sequences used in the analysis are from Pseudotsuga menziesii (PmTUA1, AAV92379), Gossypium hirsutum (GhTUA1, AY345603), Oryza sativa (OsTUA1, Os03g0726100), and Arabidopsis thaliana (AtTUA1, At1g64740). Identical amino acid residues in this alignment are shaded in black. Possible phosphorylation sites were obtained with a PROSITE motif search: boxed amino acids are N-glycosylation sites, underlined amino acids are protein kinase C phosphorylation sites, amino acids underlined with dotted lines are casein kinase II phosphorylation sites, and the arrow indicates tubulin subunits α, β, and γ signatures.
