Pro-Leu-Ser/Thr-Pro is a consensus primary sequence for substrate protein phosphorylation. Characterization of the phosphorylation of c-myc and c-jun proteins by an epidermal growth factor receptor threonine 669 protein kinase
Open accessAbstract
A growth factor-stimulated (MAP2-related) protein kinase, ERT, that phosphorylates the epidermal growth factor receptor at Thr669 has been purified from KB human tumor cells by Northwood and co-workers (Northwood, I. C., Gonzalez, F. A., Wartmann, M., Raden, D. L., and Davis, R. J. (1991) J. Biol. Chem. 266, 15266-15276). The ERT protein kinase has a restricted substrate specificity, and the structural determinants employed for substrate recognition by this enzyme have not been defined. As an approach toward understanding the specificity of substrate phosphorylation, we have used an in vitro assay to identify additional substrates for the ERT protein kinase. In this report we describe two novel substrates: (a) the human c-myc protein at Ser62 and (b) the rat c-jun protein at Ser246. Alignment of the primary sequences surrounding the phosphorylation sites located within the epidermal growth factor receptor (Thr669), Myc (Ser62), and Jun (Ser246) demonstrated a marked similarity. The observed consensus sequence was Pro-Leu-Ser/Thr-Pro. We propose that this sequence forms part of a substrate structure that is recognized by the ERT protein kinase.

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.
