| Accession Name | Accession No. | Accession Type | Pathway Link |
| 3d_fold_model | 8 | Network | Shared_Object_3d_fold_model, PKC, MAPK, PLA2, Ras |
| This model is an annotated version of the synaptic signaling network. The primary reference is Bhalla US and Iyengar R. Science (1999) 283(5400):381-7 but several of the model pathways have been updated Bhalla US, Ram PT, Iyengar R. Science. 2002 Aug 9;297(5583):1018-23. | |||

| Phosphorylated form of PLA2. Still need to hook it up using kinases. PKA: Wightman et al JBC 257 pp6650 1982 PKC: Many refs, eg Gronich et al JBC 263 pp 16645, 1988 but see Lin etal MAPK: Lin et al, Cell 72 pp 269, 1993. Show 3x with MAPK but not PKC alone Do not know if there is a Ca requirement for active phosphorylated state. | ||||||

| This form should be 3 to 6 times as fast as the Ca-only form. I have scaled by 4x which seems to give a 5x rise. 10x raise Oct 22 12 x oct 24, changed k2 = 4 * k3 | |||||||
PLA2*-Ca acting as a Product in a reaction in 3d_fold_model 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. |

| To start off, same kinetics as the PLA2-Ca-act direct pathway. Oops ! Missed out the Ca input to this pathway first time round. Let's raise the forward rate about 3x to 5e-6. This will let us reduce the rather high rates we have used for the kenz on PLA2*-Ca. In fact, it may be that the rates are not that different, just that this pathway for getting the PLA2 to the memb is more efficien.... | |||||||
