This model is an annotated version of the synaptic signaling network. The primary reference is Bhalla US and Iyengar R. Science (1999) 283(5400):381-7 but several of the model pathways have been updated. Bhalla US Biophys J. 2002 Aug;83(2):740-52 Bhalla US J Comput Neurosci. 2002 Jul-Aug;13(1):49-62

Calcineurin A and B subunits. We assume that the A and B subunits of PP2B are always bound under physiological conditions. Tallant and Cheung '83 Biochem 22 3630-3635 have conc in many species, average for mammalian brain is around 1 uM.

CaNAB acting as a Substrate in a reaction in  Synaptic_Network 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.

going on the experience with CaM, we put the fast (high affinity) sites first. We only know (Stemmer and Klee) that the affinity is < 70 nM. Assuming 10 nM at first. This doesn't really matter much because it will always be bound at physiological Ca.
