Below is a video of two 400ns long all-atom classical molecular dynamics trajectories of Rap:Raf complex.
The "ice blue" and "orange" tubes are Rap:Raf complex with phosphorylated Serine at 39th site in Rap chain. The red/blue colored region of the tube is the Switch-I. For a context see this article:
