AMPAR | | This is a model of tight coupling between the AMPAR trafficking bistability, and the CaMKII autophosphorylation bistability. In this model, the CaMKII activity is self sustaining only when AMPAR is turned on. Further, CaMKII turns on when AMPAR is turned on. |

cAMP-PDE* acting as a Substrate in a reaction in AMPAR_CaMKII_strong_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. |

| | The rates for this are poorly constrained. In adipocytes (probably a different PDE) the dephosphorylation is complete within 15 min, but there are no intermediate time points so it could be much faster. Identity of phosphatase etc is still unknown. |
