CaRegulation, Othmer-Tang-model | | 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. |

Accession No. : 32 | CaRegulation
Pathway No. : 170 | 0.01 | 1000 | No | | This mechanism has taken a while to be more tightly confirmed as probably being the TRP channel. The channel is implemented to match experimental observations about capacitative Ca entry. Levels are unchanged from the CaReg model used to generate non-oscillatory Ca response in the IP3 metabolism network. |
capacitive_Ca_entry* 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. |

| | For non-oscillatory Ca dynamics Kd was set at 3 uM. This did not allow for Ca oscillations characteristic of the Othmer-Tang model. The rates here are constrained solely by the need to generate Othmer-Tang type Ca oscillations. |
** This is a trasport reation between compartments of different volumes. Therefore Kd is not applicable. Please Note Kf, Kb units are in number of molecules instead of concentration
