The model consists of three major pathways: Calcium-calmodulin dependent protein kinase IV (CaMKIV), Mitogen-activated protein kinase (MAPK) and Protein Phosphatase 1 (PP1). Each of these converged on CREB activation. We also modeled further interactions with Transducer of regulated CREB activity 1 (TORC1) and the protein kinase A (PKA) pathway.

	This pathway inhibits Ras when cAMP is elevated. See: Hordijk et al JBC 269:5 3534-3538 1994 Burgering et al EMBO J 12:11 4211-4220 1993 The rates are the same as used in PKA-phosph-I1

	#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.

PKA_dash_active acting as a Substrate in a reaction in  mRNA synthesis 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.
