Cell spreading on extracellular matrix proteins induces tyrosine phosphorylation of tensin
Open accessAbstract
A small number of proteins becomes tyrosine-phosphorylated in response to integrin-mediated cell adhesion to extracellular matrix proteins. Previous work has identified two of these tyrosine-phosphorylated proteins as the focal adhesion kinase and paxillin. Here we identify a third focal adhesion protein, tensin, that becomes tyrosine-phosphorylated during cell adhesion to extracellular matrix proteins. The tyrosine phosphorylation of tensin does not occur when cells adhere to plastic or polylysine and is blocked when microfilament assembly and cell spreading are inhibited with cytochalasin D. In addition, we show that other focal adhesion proteins such as talin and vinculin do not become tyrosine-phosphorylated under the same conditions of cell spreading on extracellular matrix proteins.

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.
