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

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.
