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.

	#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.
