    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. It is similar to the NonOsc_Ca_IP3metab model (accession 23) except that some enzymes have been modified to have reversible kinetics rather than Michaelis-Menten kinetics. These 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.
