    This model is an annotated version of the synaptic signaling network.
    The primary reference is Bhalla US and Iyengar R. Science (1999) 283(5400):381-7 but several of the model pathways have been updated.

    Strom et al 1990 Oncogene 5 pp 345-51 report high general expression in all tissues. Huang and Ferrell 1996 PNAS 93(19):10078 use a value of 3 nM for oocytes. Here we stick with a much higher expression based on the Strom report.

    Rate consts from Chen et al Biochem 32, 1032 (1993) k3 = 4 Km for this substrate is trickier. Specific substrates are in the uM range, so we use a higher Km here. This may be too conservative in which case PKC would have a still higher effect on raf. The presence of this phosphorylation and activation step is from Kolch et al 1993 Nature 364:249
