Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
AMPAR_CaMKII_ weak_coupling	65	Network	Shared_Object_AMPAR_CaMKII_weak_coupling, CaMKII, CaM, PP1, PP2B, PP1_PSD, AMPAR, PKA, AC, AMPAR_memb, PP1_CaMKII_PSD, CaMKII_PSD
This is a model of weak coupling between the AMPAR traffikcing bistability, and the CaMKII autophosphorylation bistability. In this model, there are three stable states: Both off, AMPAR on, or both on. The fourth possible state: CaMKII on but AMPAR off, is not truly stable, since over the course of hours the AMPAR also turns on.

PP1-I1 acting as a Substrate in a reaction in AMPAR_CaMKII_weak_coupling 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.
