Abstract

Activation of the T-cell antigen receptor (TCR) results in tyrosine phosphorylation of the TCR zeta chain and other intracellular substrates. Two other T-cell integral membrane proteins, CD4 and CD8, are associated with the protein-tyrosine kinase (PTK), lck. Despite evidence that activation of this enzyme results in TCR-zeta chain phosphorylation, it has not been shown that the TCR activates lck. We have sought evidence that the TCR is associated with a PTK. In this study we use digitonin to solubilize a murine T-cell hybridoma and demonstrate that antibodies binding extracellular but not intracellular domains of the TCR specifically coprecipitate only the fyn PTK and not lck or yes, two other kinases found in these cells. The association of the fyn PTK with the TCR might enable the T cell to independently regulate two PTKs through surface receptors.

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.
