Intrinsic protein disorder and protein modifications in the processing of biological signals

Phillips, Aaron H, Kriwacki, Richard W·2020·Current Opinion in Structural Biology

Abstract

Eukaryotic cells are highly complex systems; however, they manage to attain this complexity with a surprisingly small number of protein products. This is due, in part, to the fact that the functions of the eukaryotic proteome can be modulated and controlled by a vast network of largely reversible post-translational modifications. Such modifications change the chemical nature of certain amino acid side chains and thereby can be used to modulate diverse protein functions such as enzyme activity and binding events. Here we review recent advances in the characterization of the native mechanisms by which cells utilize post-translational modifications to send biological signals as well as recent successes in engineering such systems. We highlight roles for protein disorder in signal propagation in these systems.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Disordered proteins and regions are characterized by broad and heterogeneous ensembles with small differences in relative conformational stabilities and low barriers.

    “Disordered proteins (regions) are characterized by broad and heterogeneous ensembles where the differences in the relative conformational stabilities are small, or even minor and the barriers are low.”

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.
