Intrinsic disorder is an essential characteristic of components in the conserved circadian circuit

November 15, 2020
Pelham, J.F., Dunlap, J.C. & Hurley, J.M. Intrinsic disorder is an essential characteristic of components in the conserved circadian circuit. Cell Commun Signal 18, 181 (2020). https://doi.org/10.1186/s12964-020-00658-y Video Abstract: Introduction The circadian circuit, a roughly 24 h molecular feedback loop, or clock, is conserved from bacteria to animals and allows for enhanced organismal survival by facilitating the anticipation of...
