Mapk signal specificity: The right place at the right time

Murphy, Leon O., Blenis, John·2006·Trends in Biochemical Sciences

Abstract

Although the mechanisms that lead to activation of the Ras, extracellular-signal-regulated kinase mitogen-activated protein kinase (Ras/ERK-MAPK) signaling pathway have been studied intensively, the fundamental principles that determine how activation of ERK signaling can result in distinct biological outcomes have only recently received attention. Factors such as cell-surface receptor density, expression of scaffolding proteins, the surrounding extracellular matrix, and the interplay between kinases and phosphatases modulate the strength and duration of ERK signaling. Furthermore, the spatial distribution and temporal qualities of ERK can markedly alter the qualitative and quantitative features of downstream signaling to immediate early genes (IEG) and the expression of IEG-encoded protein products. As a result, IEG products provide a molecular interpretation of ERK dynamics, enabling the cell to program an appropriate biological response.

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?

  • MAPKs can initiate cell death responses in the face of noxious stimuli such as palmitate and TNF-α.

    “Aside from regulating proliferation and differentiation, MAPKs can also initiate cell death responses in the face of noxious stimuli, such as palmitate and TNF-α [134,135].”

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.
