    Calcium ion oscillation in the cell without oscillations in IP3

    GoldbeterCaOscVcellRxDiagEqV3.svg

    Here are the adjustable parameters:

    • v0: influx of Ca2+ into the cell, uM/s.

    • v1: influx of Ca2into the cell from the InsP3 receptor, uM/s.

    • beta: saturation function of the receptor for InsP3 , unitless.

    • Vm2: maximum rate of Ca2+ pumping into the intracellular InsP3-insensitive store,  uM/s.

    • Vm3: maximum rate of Ca2+ released from the intracellular store, uM/s;

    • K2: Threshold constant for Ca2+ pumping, uM.

    • n: Hill function cooperativity coefficient for Ca2+ pumping into the store, unitless.  

    • m: Hill function cooperativity coefficient for Ca2+ pumping from the store, unitless.

    • Ka: threshold constant for activation, uM.

    • kf: efflux of cytosolic Ca2+ from the cell, 1/s.

    • k:  influx of extracellular Ca2+ into the cytosol, 1/s.

    • p denotes the degree of cooperativity of the activation process, unitless.

    Select Load [model name] below

     Select Start to begin the simulation.

    Interactive Element

    Select Plot to change Y axis min/max, then Reset and Play  |  Select Slider to change which constants are displayed |  Select About  for software information.

    Move the sliders to change the constants and see changes in the displayed graph in real time.

    After loading the GoldBeter model, select the 'Start' button below to simulate the model. Adjust the parameter sliders below the plot to see how they affect Ca2+ concentrations (Z, Y). The simulator only displays twelve parameters at a time. To choose others, select the 'Slider' button on the side and chose up to twelve parameters to adjust.
