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.

This forms due to basal autophosphorylation, but I think it has to be considered as a pathway even if some CaM is floating around. In either case it will tend to block further binding of CaM, and will not display any enzyme activity. See Hanson and Schulman JBC 267:24 pp17216-17224 1992

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.
