There are four varieties of incoherent feedforward (FF) control in a three-node system [5, 23]. In this paper, we study the incoherent feedforward loop Type 1 (I1-FFL) motif, in which the input signal (X) activates both the intermediate (Y) and the ultimate output (Z), while Y represses Z (Fig. 1a) [12]. Our model is one of … See more Previous analysis of the above model (Eqs. 1–3) showed that I1-FFL transcriptional regulation can, under the right conditions, act as a fold-change detector (FCD) [12].
