Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
NonOsc_Ca_ IP3metabolism	23	Network	MIPP, CaMKII, CaM, PKC, IP3-3K, CaRegulation, Gq, PLCbeta, 134_dephos, 145_dephos, IP4-system, IHP-system, 1345_dephos
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.

DIPP1 acting as a Substrate in a reaction in NonOsc_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.
