    This network models detailed metabolism of Ins(145)P3, integrated with GPCR mediated PLCbeta activation and Ca release by the InsP3 receptor in the neuron. The calcium response is non-oscillatory. Mishra J, Bhalla US. Biophys J. 2002 Sep;83(3):1298-316.

    LOT of this present in the cell: upto 1% of total protein mass. (Alberts et al, Mol Biol of the Cell, Garland Publishers) says 25 uM. Meyer et al, Science 256; 1992: 1199-1202 refer to studies saying it is comparable to CaMK levels. (Kakiuchi et al, J Biochem 92; 1982; 1041-48) say conc in cerebral cortex & cerebellum homogenates: 20-30uM Lower conc in other tissues: lung, adrenal gland, liver, kidney, spleen = 6,5,5,3,2 uM respectively

    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.

    We use the Martin et al 1985 Eur J Biochem 151(3):543-550 rates here, plus the Drabikowski and Brzeska 1982 JBC 257(19):11584-11590 binding consts. All are scaled by 3X to cell temperature. kf = 2e-10 kb = 72 Stemmer & Klee 1994 Biochem 33:6859-6866 have values of : K1=.9, K2=1.1. Assume 1.0uM for both
