Structure and function of the insulin receptor-a personal perspective

Abstract

Immunoprecipitation with autoantibodies to the insulin receptor derived from patients with extreme insulin resistance and acanthosis nigricans revealed that the receptor is comprised of two subunits of 135 kDa (α subunit) and 95 kDa (β subunit) and that insulin induces the rapid phosphorylation of the β subunit in intact cells. Incubation of a highly purified insulin receptor preparation with [γ-32P]ATP also resulted in tyrosine phosphorylation of the β subunit in an insulin-dependent manner, suggesting that the receptor itself is a tyrosine-specific protein kinase. Furthermore, a Japanese boy with insulin resistance and acanthosis nigricans was found to be heterozygous for a mutation of the insulin receptor gene that resulted in the replacement of glycine-996 with valine in the ATP binding site of the receptor. Expression of the mutant receptor in cultured cells revealed it to be deficient in tyrosine kinase activity and mediation of insulin action, suggesting that the tyrosine kinase activity of the insulin receptor is essential for insulin action in vivo.

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

  • Any impairments occur on main phosphorylation sites will reduce insulin receptor tyrosine kinase activity, eventually affecting the insulin function.

    “Therefore, any impairments occur on main phosphorylation sites will reduce insulin receptor tyrosine kinase activity, eventually affecting the insulin function (88–90).”

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.
