Dynamic protein–DNA recognition: beyond what can be seen

Abstract

Traditionally, specific DNA recognition is thought to rely on static contacts with the bases or phosphates. Recent results, however, indicate that residues far outside the binding context can crucially influence selectivity or binding affinity via transient, dynamic interactions with the DNA binding interface. These regions usually do not adopt a well-defined structure, even when bound to DNA, and thus form a fuzzy complex. Here, we propose the existence of a dynamic DNA readout mechanism, wherein distant segments modulate conformational preferences, flexibility or spacing of the DNA binding motifs or serve as competitive partners. Despite their low sequence similarity, these intrinsically disordered regions are often conserved at the structural level, and exploited for regulation of the transcription machinery via protein-protein interactions, post-translational modifications or alternative splicing.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
