Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
Osc_Ca_ IP3metabolism	24	Network	MIPP, CaMKII, CaM, PKC, IP3-3K, Gq, PLCbeta, 134_dephos, 145_dephos, IP4-system, IHP-system, 1345_dephos, 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.

DIPP1 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.
