    This network models an oscillatory calcium response to GPCR mediated PLCbeta activation, alongwith detailed InsP3 metabolism in the neuron. It is similar to the Osc_Ca_IP3metab model (accession 24) except that some enzymes in the InsP3 metabolism network have been modified to have reversible kinetics rather than Michaelis-Menten kinetics. The modified enzymes belong to the groups: IP4-system, IP3-3K, 145_dephos and 134_dephos. Mishra J, Bhalla US. Biophys J. 2002 Sep;83(3):1298-316.

    This represents the blocked state of the receptor when bound to a competitive antagonist. Note that this is in the Gq bound form. Simulations had shown that with the available rates, the blocking was minimal if only the unbound receptor could bind the antagonist.

    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.

    The rate consts give a total binding affinity of under 0.2 nM, good for a strong antagonist.
