Abstract

The circadian clock in Drosophila is regulated by post-translational modifications and degradation of core clock proteins through the .

  • Circadian rhythms are well understood at the molecular level in Drosophila.
  • Post-translational modifications play a key role in regulating core clock proteins.
  • The ubiquitin-proteasome system is involved in the degradation of these proteins.
  • Proteasome-mediated degradation may influence both circadian clock regulation and sleep amount.
  • E3 ubiquitin ligases could interact with mechanisms regulating circadian and homeostatic sleep.
