The authors present a model for circadian oscillations of the Period (PER) and Timeless (TIM) proteins in Drosophila. The model for the circadian clock is based on multiple phosphorylation of PER and TIM and on the negative feedback exerted by a nuclear PER-TIM complex on the transcription of the perand tim genes. Periodic behavior occurs in a large domain of parameter space in the form of limit cycle oscillations. These sustained oscillations occur in conditions corresponding to continuous…

Chaos and birhythmicity in a model for circadian oscillations of the PER and TIM proteins in drosophila
TLDR
It is shown that for constant environmental conditions this model is capable of generating autonomous chaotic oscillations and can also display birhythmicity, i.e. the coexistence between two stable regimes of limit cycle oscillations.
Theoretical models for circadian rhythms in Neurospora and Drosophila.
Limit Cycle Models for Circadian Rhythms Based on Transcriptional Regulation in Drosophila and Neurospora
TLDR
The model for Drosophila shows that when applied at the appropriate phase, light pulses of appropriate duration and magnitude can permanently or transiently suppress circadian rhythmicity and investigates the effects of the magnitude of light-induced changes on oscillatory behavior.

TLDR
The model provides a molecular dynamical explanation for the permanent or transient suppression of circadian rhythmicity triggered in a variety of organisms by a critical pulse of light.
Stochastic models for circadian oscillations: Emergence of a biological rhythm
TLDR
Stochastic simulations indicate that robust circadian oscillations can emerge at the cellular level, even when the maximum numbers of mRNA and protein molecules involved in the oscillations are of the order of only a few tens or hundreds.
Dependence of the period on the rate of protein degradation in minimal models for circadian oscillations
TLDR
The analysis allows us to reconcile the contradictory predictions for the dependence of the period on the clock protein degradation rate in three minimal models used to describe circadian rhythms.

TLDR
The results support the view that multiple PER phosphorylation introduces times delays which strengthen the capability of negative feedback to produce oscillations, and suggest a tentative explanation for the altered period of per mutants, in terms of variations in the rate of PER degradation.
Temperature compensation of circadian rhythms: control of the period in a model for circadian oscillations of the per protein in Drosophila.
TLDR
The factors affecting the period are examined in a model for circadian oscillations of the period protein (PER) in Drosophila and the results are used to address the possible bases of the relative invariance of theperiod of oscillations with respect to temperature.
A proposal for temperature compensation of the circadian rhythm in Drosophila based on dimerization of the per protein.
TLDR
Temperature compensation in this model arises from opposing effects of temperature (T) on the rate of association of PER monomers and the rate for nuclear import of PER protein and the relationship between these opposing tendencies is revealed.
Resetting the Drosophila Clock by Photic Regulation of PER and a PER-TIM Complex
TLDR
A mechanism for how a unidirectional environmental signal elicits a bidirectional clock response is suggested.
Isolation of timeless by PER Protein Interaction: Defective Interaction Between timeless Protein and Long-Period Mutant PERL
TLDR
The cloning of complementary DNAs derived from the tim gene in a two-hybrid screen for PER-interacting proteins and the demonstration of a physical interaction between the tim protein (TIM) and PER in vitro are reported.
A light-entrainment mechanism for the Drosophila circadian clock
TLDR
The Per–Tim complex is a functional unit of the Drosophila circadian clock, and Tim degradation may be the initial response of the clock to light.
