AMPAR_traff_ model0	59	Network	Shared_Object_AMPAR_traff_model0,  CaMKII,  CaM,   PP1,  PP2B,  PP1_PSD,   PKA,  AC,  AMPAR,   AMPAR_memb
This is model 0 from Hayer and Bhalla, PLoS Comput Biol 2005. It has a bistable model of AMPAR traffick, plus a non-bistable model of CaMKII. This differs from the reference model (model 1) in that model0 lacks degradation and turno ver reactions for AMPAR.

This version is activated by Gs and by a betagamma and phosphorylation.

Reduced Km to match expt data for basal activation of AC2 by PKC. Now k1 = 2.9e-6, k2 = 72, k3 = 18 18 Feb: Raised Km to 300 based on BRENDA data. Unlikely to make much difference, given the vast amount of ATP.

AC2* acting as a Product of an Enzyme in  AMPAR_traff_model0 Network

Phorbol esters have little effect on AC1 or on the Gs-stimulation of AC2. So in this model we are only dealing with the increase in basal activation of AC2 induced by PKC k1 = 1.66e-6 k2 = 16 k3 =4

AC2* acting as a Substrate in a reaction in  AMPAR_traff_model0 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.
