Figure 5. Relevant Interactions between the SOS3-FISL/NAF Domain and the PPI Domain
A section of the structure of the regulatory domain of SOS2 and SOS3 showing the residues interacting with Arg340. The labeled residues are within 3.8 Å sphere around Arg340. The straight dashed lines stand for the hydrogen bonds. Residues belonging to the SOS3-FISL/NAF domain are depicted in green. Residues belonging to the PPI domain are depicted in orange.
