        The stochiometry is a bit off here. Each NMDAR actually binds to a holoenzyme, about 12 CaMKII subunits. But our CaMKII calculations are in terms of individual subunits. So as a hack, we put in much more NMDAR than is actually there.

        There is a LOT of this in the cell: upto 1% of total protein mass. (Alberts et al) Say 25 uM. Meyer et al Science 256 1199-1202 1992 refer to studies saying it is comparable to CaMK levels.

        Huge conc of CaMKII. In PSD it is 20-40% of protein, so we assume it is around 2.5% of protein in spine as a whole. This level is so high it is unlikely to matter much if we are off a bit. This comes to about 70 uM.

        Also known as RC3 and p17 and BICKS. Conc in brain >> 2 uM from Martzen and Slemmon J neurosci 64 92-100 1995 but others say less without any #s. Conc in dend spines is much higher than overall, so it could be anywhere from 2 uM to 50. We will estimate 10 uM as a starting point. Gerendasy et al JBC 269:35 22420-22426 1994 have a skeleton model (no numbers) indicating CaM-Ca(n) binding ....

    Pathway No. 279
    Network80.01No
        I1 is a 'mixed' inhibitor, but at high enz concs it looks like a non-compet inhibitor (Foulkes et al Eur J Biochem 132 309-313 9183). We treat it as non-compet, so it just turns the enz off without interacting with the binding site. Cohen et al ann rev bioch refer to results where conc is 1.5 to 1.8 uM. In order to get complete inhib of PP1, which is at 1.8 uM, we need >= 1.8 uM.

        This isn't explicitly present in the M&L model, but is obviously needed. I assume its conc is fixed at 1uM for now, which is a bit high. PLA2 is stim 7x by PIP2 @ 0.5 uM (Leslie and Channon BBA 1045:261(1990) Leslie and Channon say PIP2 is present at 0.1 - 0.2mol% range in membs, which comes to 50 nM. Ref is Majerus et al Cell 37 pp 701-703 1984 Lets use a lower level of 30 nM, same ref....
