Abstract

We have purified the epidermal growth factor (EGF) receptor/protein kinase from the livers of normal mice by affinity chromatography. The biochemical properties of the liver receptor are very similar to those of the EGF receptor previously prepared from the human tumor cell line A-431 [Cohen, S., Ushiro, H., Stoscheck, C. & Chinkers, M. (1982) J. Biol. Chem. 257, 1523-1531]. The liver receptor for EGF is a glycoprotein of Mr 170,000. It binds 125I-labeled EGF and possesses an EGF-stimulable protein kinase activity specific for tyrosine residues. Both autophosphorylation and kinase activity toward exogenous substrates are demonstrable. The EGF receptor purified from normal mouse liver is antigenically related to the receptor purified from human A-431 cells.

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.
