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.
