Polymorphic positions 62, 79 and 82 (asterisk), correspond to amino acids in the plant-specific binding pocket region. Position 79 (double-asterisk) is also one of the key amino acid for the profilin-actin interaction. Polymorphic positions 130 and 131 (triple-asterisk) correspond to important amino acids for the profilin-PIP interaction.
