Abstract

Perspective Figure 1 Schematic illustration of major signaling pathways of insulin action.The phosphorylated insulin receptor binds and phosphorylates IRS proteins and Shc, which bind differentially to various downstream signaling proteins.PI3-kinase is critical for metabolic actions of insulin, such as glucose transport, glycogen synthesis, and protein synthesis, whereas Grb-2/SOS complex, which activates the MAP kinase cascade, is critical in mitogenic response.PI3-kinase probably modulates the mitogenic response as well.This series continues from the March 1999, no.6, issue.

  • Phosphorylated tyrosine residues of IRS-1 mediate association with the 85-kDa regulatory subunit of PI3K, activating the enzyme.

    “The phosphorylated tyrosine residues of IRS-1 mediate an association with the 85-kDa regulatory subunit of phosphatidylinositol 3-kinase (PI3K), leading to activation of the enzyme [138–140, 143, 144].”

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.
