Before revision:  Based on the patch-clamp experimental data obtained from the outer membranes of isolated nuclei of theXenopus oocyte, we construct an allosteric competition model of single IPR channels on their native ER membrane environment.
After revision:  Based on the patch-clamp experimental data obtained from the outer membranes of isolated nuclei of theXenopus It has long been observed that the IPR channel is a typical biological system which performs adaptation. However, recent advances on the physical essence of adaptation show that adaptation systems with a negative feedback mechanism, such as the IPR channel, must break detailed balance and always operate out of equilibrium with energy dissipation. Almost all previous IPR models are equilibrium models assuming detailed balance and thus violate the physical essence of adaptation. In this article, we constructed a nonequilibrium allosteric model of single IPR channels on their native ER membrane environment.
