Structural comparison between mSAV1 WW2 231–266 and hMAGI1 WW2 355–390. (A) Structure of SAV1 WW2 231–266. (Lines) Side chains of key aromatic residues (F249, Y252, H256, Y263) buried in the interface of the homodimer; (neon bars) side chains of the polar residues (E242, S246). These side chains are colored to clarify the representation of the molecular interaction. (B) Structure of MAGI1 WW2 355–390. (Lines) Side chains of the aromatic residues (Y373, Y376, H380, Y387); (neon bars) side chains of the polar residues (E366, D370).
