Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
CaMKII_noPKA_ model3	62	Network	Shared_Object_CaMKII_noPKA_model3, CaMKII, CaM, PP1, PP2B, PP1_PSD
This is the model of CaMKII bistability, model 3. It exhibits bistability in CaMKII activation due to autophosphorylation at the PSD and local saturation of PP1. This version of model 3 does not include the full PKA regulatory pathway, and instead has a predefined initial amount of active PKA.

PP1-active acting as a Substrate in a reaction in CaMKII_noPKA_model3 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.

Let us assume that the equil in this case is very far over to the right. This is probably safe.
