Protein degradation helps control the stability of the circadian clock protein CCA1

AI simplified

Abstract

CCA1 protein stability is controlled by the proteasome.

  • The circadian clock influences various plant processes, including growth and flowering.
  • CCA1 is a key transcription factor in the circadian oscillator mechanism.
  • Proper regulation of CCA1 is crucial for maintaining oscillator function.
  • CCA1 may integrate environmental signals like temperature and light.
  • Findings highlight multiple levels of regulation affecting CCA1 stability.
