摘要

The hormone-receptor interaction is reconsidered and a minimal kinetic theory for the signal transduction in native cells is proposed. The basic equation for the time evolution of the concentration of the hormone-receptor complex is obtained. It is shown, that the hormone-receptor interaction is regulated by a cycle of G protein, i.e. kinetic parameters associated with the G protein cycle enter this equation. The existence of exponential and oscillatory regimes in kinetics of the G protein cycle, and hormone-receptor interactions are predicted. Experimental kinetic curves for agonist binding are computer-simulated, and numerical values for various kinetic and equilibrium parameters are obtained.
