Abstract

Stimulation of the interleukin-6 (IL-6) signalling pathway occurs via the IL-6 receptor–glycoprotein 130 (IL-6R–gp130) receptor complex and results in the regulation of acute-phase protein genes in liver cells. Ligand binding to the receptor complex leads to tyrosine phosphorylation and activation of Janus kinases (Jak), phosphorylation of the signal transducing subunit gp130, followed by recruitment and phosphorylation of the signal transducer and activator of transcription factors STAT3 and STAT1 and the src homology domain (SH2)-containing protein tyrosine phosphatase (SHP2). The tyrosine phosphorylated STAT factors dissociate from the receptor, dimerize and translocate to the nucleus where they bind to enhancer sequences of IL-6 target genes. Phosphorylated SHP2 is able to bind growth factor receptor bound protein (grb2) and thus might link the Jak/STAT pathway to the ras/raf/mitogen-activated protein kinase pathway. Here we present data on the dose-dependence, kinetics and kinase requirements for SHP2 phosphorylation after the activation of the signal transducer, gp130, of the IL-6-type family receptor complex. When human fibrosarcoma cell lines deficient in Jak1, Jak2 or tyrosine kinase 2 (Tyk2) were stimulated with IL-6–soluble IL-6R complexes it was found that only in Jak1-, but not in Jak 2- or Tyk2-deficient cells, SHP2 activation was greatly impaired. It is concluded that Jak1 is required for the tyrosine phosphorylation of SHP2. This phosphorylation depends on Tyr-759 in the cytoplasmatic domain of gp130, since a Tyr-759 → Phe exchange abrogates SHP2 activation and in turn leads to elevated and prolonged STAT3 and STAT1 activation as well as enhanced acute-phase protein gene induction. Therefore, SHP2 plays an important role in acute-phase gene regulation.

  • SHP2 is rapidly recruited to gp130 and phosphorylated by JAKs, which hints to a function as early feedback inhibitor.

    “In response to IL-6 SHP2 is rapidly recruited to gp130 [8] and phosphorylated by JAKs [11], which hints to a function as early feedback inhibitor.”

    From The tyrosine phosphatase SHP2 increases robustness and information transfer within IL-6-induced JAK/STAT signalling (2021) · cites this paper as [11]

    The Introduction reports transient SHP2 phosphorylation alongside gp130 activation and SHP2–gp130 complex formation, and describes SHP2 as inhibitory. In “SHP2 phosphorylation requires specific Jaks,” the paper finds that Jak1 is required but says it cannot determine whether Jak1 phosphorylates SHP2 directly or another kinase does so. Thus it supports JAK-dependent phosphorylation, but not an unqualified claim that JAKs themselves phosphorylate SHP2. Page numbers are unavailable in our copy. (LLM, conf=0.88)

  • The lack of influence of SHP2 on robustness of late IL-6-induced STAT3 activation might be explained by the fact that SHP2 itself is phosphorylated rapidly in response to IL-6, which causes dissociation from gp130.

    “The lack of influence of SHP2 on robustness of late IL-6-induced STAT3 activation (Fig. 4) might be explained by the fact that SHP2 itself is phosphorylated rapidly in response to IL-6 (Fig. 1b) which causes dissociation from gp130 [9–11].”

    From The tyrosine phosphatase SHP2 increases robustness and information transfer within IL-6-induced JAK/STAT signalling (2021) · cites this paper as [11]

    In “The time-course of SHP2 phosphorylation corresponds to that of gp130” (page unavailable), SHP2 phosphorylation is detected five minutes after IL-6 stimulation, and SHP2–gp130 complex formation follows the phosphorylation time courses. The paper does not establish that phosphorylation of SHP2 causes it to dissociate from gp130; gp130 phosphorylation also declines over that period. (LLM, conf=0.85)

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.
