CaRegulation, Othmer-Tang-model | | This network models an oscillatory calcium response to GPCR mediated PLCbeta activation, alongwith detailed InsP3 metabolism in the neuron. It differs from the NonOsc_Ca_IP3metabolism network in the CaRegulation module and in InsP3 receptor kinetics. Details of InsP3 receptor kinetics have been adapted from the Othmer-Tang model for oscillatory Ca dynamics. Mishra J, Bhalla US. Biophys J. 2002 Sep;83(3):1298-316. |

IP_1pase acting as a Substrate in a reaction in Osc_Ca_IP3metabolism 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. |
