Daily rhythms of behavior and physiology arise from endogenous circadian clocks. At the molecular level, the circadian clock consists of intricate transcriptional and post-transcriptional feedback loops that drive 24h rhythms in a vast repertoire of basic cellular processes. The nuclear envelope, as a fundamental component of the cell, has been shown to function as a global transcriptional regulatory machinery. Recently we found that nuclear envelope proteins regulate the circadian clock both in the mammalian system and in fruit flies. One of these proteins, MAN1, impinges on the clock by binding to the promoter region of the core clock gene BMAL1 and enhances its transcription. Here we discuss about other potential mechanisms employed by nuclear envelope proteins to regulate the circadian clock and possible biological relevance of these modulations.
