在这里,三维模型的建立和分子动力学模拟的促黄体生成激素受体已被用来产生假说的分子机制的激活受体诱导的自然发生的激活突变。野生型受体和16个组成型活性或非活性突变体的比较分析一直有助于推断的结构/动力学特征,可以表征非活性和活性形式的受体。这些特征也被用于预测新受体突变体的功能行为。本研究的结果可能提供一个结构框架来解释由黄体生成素受体突变引起的病理效应。此外,所提出的理论模型可能是有用的工程新的突变或配体能够调节受体功能。
Here, three-dimensional model building and molecular dynamics simulations of the luteinizing hormone receptor have been employed to generate hypotheses about the molecular mechanisms underlying the activation of the receptor induced by naturally occurring activating mutations. The comparative analysis of the wild-type receptor and of 16 constitutively active or inactive mutants has been instrumental in inferring the structural/dynamic features which could characterize the inactive and the active forms of the receptor. These features have been also employed for predicting the functional behavior of new receptor mutants. The results of this study might provide a structural framework to interpret the pathological effects induced by mutations of the luteinizing hormone receptor. In addition, the proposed theoretical model could be useful for engineering new mutations or ligands able to modulate receptor function.
