Figure 4From: The Puf family of RNA-binding proteins in plants: phylogeny, structural modeling, activity and subcellular localizationAlignment of amino acids in the PUM-HD that are predicted to interact with RNA bases. Sequence alignment of amino acid triplets at positions 12, 13 and 16 in each Puf repeat (R1 to R8) from the Arabidopsis and rice Puf proteins. Black shading identifies amino acids that are identical to the human Pum1 protein.Back to article page
