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.

	#s from Bramson et al CRC crit rev Biochem 15:2 93-124. They have a huge list of peptide substrates and I have chosen high-ish rates. These consts give too much PKA activity, so lower Vmax 1/3. Now, k1 = 3e-5, k2 = 36, k3 = 9 (still pretty fast). Also lower Km 1/3 so k1 = 1e-5 Cohen et al FEBS Lett 76:182-86 1977 say rate =30% PKA act on phosphokinase beta.

PKA-active 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.
