Abstract

Interleukin-2 (IL-2) binds to two distinct receptor molecules, the IL-2 receptor α (IL-2Rα, p55) chain and the newly identified IL-2 receptor β (IL-2Rβ, p70-75) chain. The cDNA encoding the human IL-2Rβ chain has now been isolated. The overall primary structure of the IL-2Rβ chain shows no apparent homology to other known receptors. Unlike the IL-2Rα chain, the IL-2Rβ chain has a large cytoplasmic region in which a functional domain (or domains) mediating an intracellular signal transduction pathway (or pathways) may be embodied. The cDNA-encoded β chain binds and internalizes IL-2 when expressed on T lymphoid cells but not fibroblast cells. Furthermore, the cDNA gives rise to the generation of high-affinity IL-2 receptor when co-expressed with the IL-2Rα chain cDNA.

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.
