生物钟基因是动物 24 小时内部计时的分子基础。哺乳动物大脑昼夜节律起搏器(即 SCN)内部和外部的时钟基因表达将时间信息整合到丰富的生理过程中。大量数据表明,除了典型的细胞计时功能外,时钟蛋白还与参与与计时无关的细胞过程的蛋白质相互作用,包括蛋白质调节以及与与昼夜节律调节不直接相关的其他信号传导机制的相互作用。事实上,最近的数据表明,视交叉上核之外的时钟基因参与了基本的大脑过程,如睡眠/觉醒、压力和记忆。时钟基因在这些大脑过程中的作用复杂且多样,影响许多分子途径和表型。在这篇综述中,我们将讨论最近关于时钟基因与睡眠、压力和记忆的关系的研究。此外,我们提出了一个有争议的可能性,即这些功能在某些情况下可能独立于其昼夜节律计时功能。
Circadian clock genes serve as the molecular basis for animals’ ~24-h internal timekeeping. Clock gene expression inside and outside of the mammalian brain’s circadian pacemaker (i.e. the SCN) integrates temporal information into a wealth of physiological processes. Ample data suggests that in addition to canonical cellular timekeeping functions, clock proteins also interact with proteins involved in cellular processes not related to timekeeping, including protein regulation and the interaction with other signaling mechanisms not directly linked to the regulation of circadian rhythms. Indeed, recent data suggests that clock genes outside the SCN are involved in fundamental brain processes such as sleep/wakefulness, stress and memory. The role of clock genes in these brain processes are complex and divers, influencing many molecular pathways and phenotypes. In this review, we will discuss recent work on the involvement of clock genes in sleep, stress, and memory. Moreover, we raise the controversial possibility that these functions may be under certain circumstances independent of their circadian timekeeping function.
