How the stability of a key clock protein relates to temperature balance in Neurospora's daily rhythm

Abstract
Experimental findings show that the stability of the FRQ protein is crucial for the temperature compensation of Neurospora crassa's circadian rhythm.
- Temperature compensation is an important characteristic of biological clocks.
- In Neurospora crassa, the FRQ protein regulates the transcription of the frequency (frq) gene through negative feedback.
- The stability of FRQ protein influences both the period length of the circadian rhythm and its temperature compensation.
- Experimental measurements of FRQ protein stabilities in frq mutants at 20 degrees C and 25 degrees C align with earlier model predictions.
- The partial loss of temperature compensation in frq7 and frq(S513I) mutants can be explained using the Goodwin oscillator model when activation energies for FRQ degradation are included.
