| This is the model file for figure 3 from Bhalla US and Iyengar R. Science (1999) 283(5400):381-7. It is a model of the Ca activation of CaMKII and other CaM-activated enzymes. It includes the regulatory phosphatases PP1 and PP2B (Calcineurin) acting on CaMKII and also includes CaM-activated adenylyl cyclase and PKA in the synapse. Demonstration script files for generating the figures in the paper, including figure 3, are available here. | |||

| PKA: Protein kinase activated by cAMP. R2C2 complex consists of 2 catalytic (C) subunits, and the R-dimer. There are two types of cAMP binding sites termed A and B according to the rate with which they exchange bound labelled nucleotide. Dagfinn Ogreid and Stein Ove Doskeland (1981) Int.J.Biochem. 13(1):1-19 Physiological concentration of PKA = 0.59 uM (cardiac myocyte) Jeffrey J.

R2C2 acting as a Substrate in a reaction in fig3_CaMKII 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. |
