反应调节蛋白利用其非活性和活性构象中的不同分子表面用于抑制或激活效应结构域活性的多种调节性分子内和/或分子间蛋白质-蛋白质相互作用。这种多功能的策略使众多的调节机制之间的反应调节。最近积累的非活性和活性形式的多域反应调节剂和反应调节剂复合物的结构已经揭示了许多不同的结构域的安排,提供了深入的监管机制。虽然多样性是规则,即使在含有同源结构域的亚家族成员中,也经常出现几种相互作用的结构模式和调节机制。这些主题涉及在受体结构域的α4-β5-α5面的相互作用、受体结构域的二聚化模式以及抑制或激活异源结构域相互作用。
Response regulator proteins exploit different molecular surfaces in their inactive and active conformations for a variety of regulatory intra- and/or intermolecular protein-protein interactions that either inhibit or activate effector domain activities. This versatile strategy enables numerous regulatory mechanisms among response regulators. The recent accumulation of structures of inactive and active forms of multi-domain response regulators and response regulator complexes has revealed many different domain arrangements that have provided insight into regulatory mechanisms. Although diversity is the rule, even among subfamily members containing homologous domains, several structural modes of interaction and mechanisms of regulation recur frequently. These themes involve interactions at the α4-β5-α5 face of the receiver domain, modes of dimerization of receiver domains, and inhibitory or activating hetero-domain interactions.
