Summary of structural variation in plant FH2 domains. Structure of the yeast Bni1p FH2 domain (PDB 1UX5), with marked positions of major insertions (arrows), deletions (flags pointing towards the missing portion of sequence) and conserved site mutations (colored balls) found in Arabidopsis formins. Grey balls denote positions of insertions found in multiple proteins, numbers correspond to conserved amino acid positions in Bni1p.
