Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
NonOsc_Ca_ IP3metabolism	31	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. 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.

Name	Accession Name	Pathway Name	Initial Conc. (uM)	Volume (fL)	Buffered
MIPP	NonOsc_Ca_ IP3metabolism Accession No. : 31	MIPP Pathway No. : 144	0.398	160	No
Multiple Inositol Polyphosphate Phosphatase from Nogimori et al, JBC 266(25); 1991: 16499-506 MIPP clustered in ER. Distinct transporters present for cytosolic substrates. Accounts for 30-45% of total 3-phosphatase activity against substrates, hence cytosolic counterparts of this enzyme must be present (as per Chi et al, MCB 20; 2000: 6496-507)
