This is a non-bistable model of ERKII signaling that also incorporates PKM synthesis triggered by Ca influx. It is a simplified variant of the model of Ajay SM, Bhalla US. Eur J Neurosci. 2004 Nov;20(10):2671-80.

Raf-GTP-Ras acting as a Product in a reaction in  Ajay_Bhalla_2007_PKM 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.

18 May 2003. This reaction is here to provide basal activity for MAPK as well as the potential for direct EGF stimulus without PKC activation. Based on model from FB/fb28c.g: the model used for MKP-1 turnover. The rates there were constrained by basal activity values.
