How cells control daily body clocks after gene activation

Post-transcriptional regulation is crucial for robust circadian rhythms across various organisms.

• Circadian rhythms are present in most living organisms and are generated by conserved molecular mechanisms.
• Core circadian clocks consist of multiple regulatory feedback loops that require precise coordination.
• Post-transcriptional regulation has been shown to significantly affect the phase and amplitude of mRNA and protein expression.
• Current knowledge highlights the role of post-transcriptional mechanisms in the modulation of circadian gene expression in dinoflagellates, plants, fungi, and animals.
• Understanding these regulatory processes is important for maintaining the stability of circadian rhythms.
