Fig. 13From: Detection of biological switches using the method of Gröebner basesBistability of a three-dimensional RAS model. The system has two stable fixed points (blue stars) and an unstable saddle-point (magenta circle). Trajectories reach the stable fixed points after following the unstable manifold of the saddle point. S is the Shc-Grb2-SOS complex. RT is RASGTP. SRT is the SOS-RASGTP complexBack to article page
