| Model for figure 1c in Bhalla US et al. Science (2002) 297(5583):1018-23. The demo for this figure is available here. This synaptic signaling model is without the MKP-1 feedback, so it is bistable and remains so over long periods. | |||

| Berkers et al JBC 266 say 22K high affinity receptors per cell. Sherrill and Kyte Biochemistry 35 use range 4-200 nM. These values match reasonably. Heidaran et al 1993 JBC 268(13):9287-9295 use NIH3T3 cells and have 6.5e4 receptors/cell. This is also in the same general range. We use this last value because the cell type matches. | ||||||
PDGFR acting as a Substrate in a reaction in MAPK-bistability-fig1c Network
| Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider. |
