细胞质多聚腺苷化元件结合蛋白(CPEB)家族在模式生物突触可塑性和记忆的建立中起着至关重要的作用。在这篇综述中,我们引用了来自行为学、电生理学和形态学研究的证据,概述了CPEB3作为学习和记忆的关键调节因子的证据。随后,CPEB3的调节作用在可塑性相关蛋白的背景下被阐述,包括AMPA和NMDA受体亚单位,肌动蛋白,以及突触支架蛋白PSD95。最后,我们深入研究了一些更好的分子机制,这些机制指导了这种动态调节因子在突触刺激和基础状态下的功能,包括各种上游调节因子、翻译后修饰和赋予CPEB3独特性质的重要结构域。综上所述,这篇综述全面介绍了CPEB3的S维持翻译控制所需的调节层,该途径指导建立和维持持久突触可塑性以及最终长期学习和记忆所需的必要蛋白质变化。
The cytoplasmic polyadenylation element-binding (CPEB) protein family have demonstrated a crucial role for establishing synaptic plasticity and memory in model organisms. In this review, we outline evidence for CPEB3 as a crucial regulator of learning and memory, citing evidence from behavioral, electrophysiological and morphological studies. Subsequently, the regulatory role of CPEB3 is addressed in the context of the plasticity-related proteins, including AMPA and NMDA receptor subunits, actin, and the synaptic scaffolding protein PSD95. Finally, we delve into some of the more well-studied molecular mechanisms that guide the functionality of this dynamic regulator both during synaptic stimulation and in its basal state, including a variety of upstream regulators, post-translational modifications, and important structural domains that confer the unique properties of CPEB3. Collectively, this review offers a comprehensive view of the regulatory layers that allow a pathway for CPEB3’s maintenance of translational control that guides the necessary protein changes required for the establishment and maintenance of lasting synaptic plasticity and ultimately, long term learning and memory.
