(A) Radial cladogram of the Arabidopsis NET protein superfamily. Protein sequences fall into four distinct clades or families. (B) NAB domain protein sequence alignment. ClustalX default residue coloring scheme based on physiochemical properties. Consensus secondary structure is shown below. Cylinders represent α helices, green sections show β turns, and green arrow represents β sheet. (C) Heatmap of NET family transcript level profiles. Adapted from publicly available DNA microarray data visualized with gene investigator.
