Genesis "Signs and Seasons" - the Circadian Rhythm
Intrinsically Disordered Proteins guides animal development The role of IDPs (intrinsically disordered proteins) in the circadian rhythm is an exciting area of research, and there's growing evidence to suggest that they played a crucial role in the development of animals circadian rhythms. What are IDPs and how are they linked to the circadian rhythm? IDPs are proteins that lack a defined, stable 3D structure. This flexibility allows them to interact with a variety of other proteins and molecules in different ways, depending on the cellular environment and the presence of modifying factors like phosphorylation. This makes them ideal for complex regulatory processes like the circadian rhythm, which relies on a network of interlocking feedback loops to keep track of time. In the circadian clock, IDPs play several key roles: Timing: Some IDPs, like the protein FRQ in cyanobacteria and Neurospora, have built-in "delay lines" that slow down their own degradation o...
