WebJan 4, 2024 · Specifically, we propose that an incoherent feedback loop mechanism, besides high redundancy, mediates robustness of expression of broadly expressed genes, and we show how redundancy may be a consequence of motif turnover in regulatory sequences, instead of the result of natural selection favouring robustness. Methods Webfind that incoherent FFLs can serve as a novel mechanism for accelerating the expression of the target genes. Both coherent and incoherent FFL behavior is sign sensitive: they accelerate or This paper was submitted directly (Track II) to the PNAS ofﬁce.
