Figure 2: Sequence alignment of full-length IRX proteins using Clustal omega. The highlighted sequence is the homeodomain in the IRX proteins. Hydrophobic amino acids (A, V, F, P, M, I, L and W) are coloured red. Acidic amino acids (D and E) are coloured blue. Basic amino acids (R, H and K)-magenta, Others (S, T, Y, H, C, N, G and Q) are green.
