We know that the steady-state amount of Rec-Gq should be 40% of the total amount of receptor. This is for a different receptor, still we can try to match the value. kf = 1e-6 and kb = 1 give 0.333:0.8 which is pretty close. 209.306834707 -401.256123603 white 15 kinetics_1702_0_ * Rec_bind_Gq_2350_0__Kf * G_GDP_2360_0_*mGluR_2334_0_-kinetics_1702_0_ * Rec_bind_Gq_2350_0__Kb * Rec_Gq_2338_0_ $\mathrm{kinetics\_1702\_0\_}\mathrm{Rec\_bind\_Gq\_2350\_0\_\_Kf}\mathrm{G\_GDP\_2360\_0\_}\mathrm{mGluR\_2334\_0\_}-\mathrm{kinetics\_1702\_0\_}\mathrm{Rec\_bind\_Gq\_2350\_0\_\_Kb}\mathrm{Rec\_Gq\_2338\_0\_}$ kf = kg1 = 0.01/sec, kb = 0.

The binding of IP3 on this reaction had a Hill coeff of 3. The eqns of Mahama and Linderman (cited in the book as 1993 a) are equivalent to the binding all occurring in a single step, so that is how I do it in this version. Their Ki1 is 0.07 uM. Lots of other data sources: Ramos-Franco et al, Biophys J 75, 1998: 834-39 have Ca sensitivity curves. At 250 nM free Ca, the EC50 for type1 is 58 nM and type 2 is 194 nM. Type 3 would be about 2 uM according to Newton et al, JBC 268(46), 1994: 28613-19. For the purposes of this model we use a Kd of 2.7 uM which is high but maybe OK at low calcium. The details of Ca interaction with the IP3R are not included in this model. 557.440620456 -410.400703429 white darkgreen kinetics_1702_0_ * IP3Rbind_2459_0__Kf * IP3R_2457_0_*IP3_1844_0_^3-kinetics_1702_0_ * IP3Rbind_2459_0__Kb * IP3R_p_2461_0_ $\mathrm{kinetics\_1702\_0\_}\mathrm{IP3Rbind\_2459\_0\_\_Kf}\mathrm{IP3R\_2457\_0\_}\mathrm{IP3\_1844\_0\_}^3-\mathrm{kinetics\_1702\_0\_}\mathrm{IP3Rbind\_2459\_0\_\_Kb}\mathrm{IP3R\_p\_2461\_0\_}$ The Kd is set at about 3 uM so that at resting Ca the capacitative Ca entry is almost blocked.

It includes 3 compartments: extracellular, intracellular and the Ca stores. Ca pumps that pump out Ca from cytoplasm to extracellular space and into stores, are balanced by leak channels from the stores and extracellular space. The IP3 receptor and capacitative entry channels drive Ca under influence of different stimuli. Model includes the Ca buffer - Calsequestrin in the stores. The model is a little artificial on IP3R kinetics, and does not include the influence of Ca on IP3R. kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFFF00 PMID 18957214 Neuron 2008. Phospho-FMRP binds to and inhibits protein translation cplx. mGluR1/5 activation causes dephosph and release of this inhibition. There is also a suggesiton of FMRP degradation following this dephosph. kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500 kinetics_1702_0_ kinetics_1702_0_ #FFA500
