Description

This model of the Neurospora circadian clock illustrates how the parallel, temperature-dependent FRQ feedback loops can give rise to temperature compensation and period control through isoform switching. This model is an extension of an existing model by Leloup et al. (PMID: 10643740). The model involves only the frq gene and demonstrates that the isoform switching mechanism is not specific to a particular set of equations.
