蛋白质在细胞间和细胞内以及细胞外部和内部的信号传递中起中介作用。信号蛋白的动态特性对其功能至关重要。我们讨论了蛋白质动力学在信号传递中的作用的新兴范例。一个中心原则是,蛋白质在进化选择的能量景观上的许多状态之间波动。上游信号重塑了这一格局,导致信号蛋白向下游伙伴传递信息。新的方法提供了在原子尺度上对信号蛋白质的动态性质的洞察。信号层次结构的下一个阶段--多个信号如何整合,以及细胞信号通路如何在空间和时间上组织--对未来提出了激动人心的挑战,需要大胆的多学科方法。
Proteins mediate transmission of signals along intercellular and intracellular pathways and between the exterior and the interior of a cell. The dynamic properties of signaling proteins are crucial to their functions. We discuss emerging paradigms for the role of protein dynamics in signaling. A central tenet is that proteins fluctuate among many states on evolutionarily selected energy landscapes. Upstream signals remodel this landscape, causing signaling proteins to transmit information to downstream partners. New methods provide insight into the dynamic properties of signaling proteins at the atomic scale. The next stages in the signaling hierarchy—how multiple signals are integrated and how cellular signaling pathways are organized in space and time—present exciting challenges for the future, requiring bold multidisciplinary approaches.
