Epistatic coupling
WebJun 23, 2016 · This analysis highlights two important properties of epistasis: (1) the lack of any epistatic interactions between mutations dramatically simplifies the description of multiple mutations to just the sum over the underlying single mutation effects, and (2) the absence of lower-order epistatic interactions (e.g., Δ 2G, = 0) does not imply absence … WebAug 10, 2024 · Epistasis shapes evolutionary trajectories.

WebDec 9, 2024 · We measure the time-autocorrelation of fluctuations in the likelihood of DRMs due to epistatic coupling with the sequence background, which reveals the presence of two evolutionary processes controlling DRM kinetics with two distinct time scales. WebMay 24, 2024 · Here, we propose a complementary approach: we develop strategies to randomize or resample sequence data, such that conservation patterns and phylogenetic relations are preserved, while intrinsic (i.e. structure- or function-based) coevolutionary couplings are removed.
