Complementary research in synthetic biology has introduced oscillators in vivo and in vitro suggesting that robust oscillation can be recapitulated using a small number of biochemical components. In this work, we introduce signaling crosstalk in biocircuits as a consequence of enzyme-mediated biochemical reactions. As a motivating example, we consider an in vitro oscillator with two types of crosstalk: crosstalk in production and degradation of RNA signals. We then pose a framework for quantifying crosstalk and use it to derive several dynamical constraints and suggest design techniques for ameliorating crosstalk in in vitro biochemical systems. As an example, we show that the balance between production and degradation crosstalk plays a key role in determining system stability, potentially leading to loss of oscillatory behavior. We demonstrate that the effects of crosstalk can attenuated through the effective tuning of two key parameters in order to recover desired system dynamics.
