Control of time-dependent biological processes by temporally patterned input.

Temporal patterning of biological variables, in the form of oscillations and rhythms on many time scales, is ubiquitous. Altering the temporal pattern of an input variable greatly affects the output of many biological processes. We develop here a conceptual framework for a quantitative understanding of such pattern dependence, focusing particularly on nonlinear, saturable, time-dependent processes that abound in biophysics, biochemistry, and physiology. We show theoretically that pattern dependence is governed by the nonlinearity of the input-output transformation as well as its time constant. As a result, only patterns on certain time scales permit the expression of pattern dependence, and processes with different time constants can respond preferentially to different patterns. This has implications for temporal coding and decoding, and allows differential control of processes through pattern. We show how pattern dependence can be quantitatively predicted using only information from steady, unpatterned input. To apply our ideas, we analyze, in an experimental example, how muscle contraction depends on the pattern of motorneuron firing.

Alternative initiation of translation and time-specific phosphorylation yield multiple forms of the essential clock protein FREQUENCY.

The frequency (frq) gene encodes central components of the transcription/translation-based negative-feedback loop comprising the core of the Neurospora circadian oscillator; posttranscriptional regulation associated with FRQ is surprisingly complex. Alternative use of translation initiation sites gives rise to two forms of FRQ whose levels peak 4-6 hr following the peak of frq transcript. Each form of FRQ is progressively phosphorylated over the course of the day, thus providing a number of temporally distinct FRQ products. The kinetics of these regulatory processes suggest a view of the clock where relatively rapid events involving translational regulation in the synthesis of FRQ and negative feedback of FRQ on frq transcript levels are followed by slower posttranslational regulation, ultimately driving the turnover of FRQ and reactivation of the frq gene.

Thermally regulated translational control of FRQ mediates aspects of temperature responses in the neurospora circadian clock.

Two forms of FRQ, a central component of the Neurospora circadian clock, arise through alternative in-frame initiation of translation. Either form alone suffices for a functional clock at some temperatures, but both are always necessary for robust rhythmicity. Temperature regulates the ratio of FRQ forms by favoring different initiation codons at different temperatures; when either initiation codon is eliminated, the temperature range permissive for rhythmicity is demonstrably reduced. This temperature-influenced choice of translation-initiation site represents a novel adaptive mechanism that extends the physiological temperature range over which clocks function. Additionally, a temperature-dependent threshold level of FRQ is required to establish the feedback loop comprising the oscillator. These data may explain how temperature limits permissive for rhythmicity are established, thus providing a molecular understanding for a basic characteristic of circadian clocks.
