1 Two tyrosine phosphoproteins in phorbol ester-sensitive EL4 (S-EL4) mouse thymoma cells have been identified as the p120 c-Cbl protooncogene product and the p85 subunit of phosphatidylinositol 3-kinase. Phorbol Esters extracellular matrix protein 1 Mus musculus
2 Tyrosine phosphorylation of p120 and p85 increased rapidly after phorbol ester stimulation. Tyrosine extracellular matrix protein 1 Mus musculus
3 Tyrosine phosphorylation of p120 and p85 increased rapidly after phorbol ester stimulation. Phorbol Esters extracellular matrix protein 1 Mus musculus
4 Co-immunoprecipitation experiments revealed complexes of c-Cbl with p85, and of p85 with the tyrosine kinase Lck in phorbol ester-stimulated S-EL4 but not in unstimulated S-EL4 or in R-EL4 cells. Phorbol Esters extracellular matrix protein 1 Mus musculus
5 Co-immunoprecipitation experiments revealed complexes of c-Cbl with p85, and of p85 with the tyrosine kinase Lck in phorbol ester-stimulated S-EL4 but not in unstimulated S-EL4 or in R-EL4 cells. Phorbol Esters extracellular matrix protein 1 Mus musculus
6 In vitro kinase assays revealed phosphorylation of p85 by Lck only in phorbol ester-stimulated S-EL4 cells. Phorbol Esters extracellular matrix protein 1 Mus musculus
7 Greatly decreased tyrosine phosphorylation of c-Cbl and p85 in the complexes may contribute to the failure of R-EL4 cells to respond to phorbol ester. Tyrosine extracellular matrix protein 1 Mus musculus
8 Greatly decreased tyrosine phosphorylation of c-Cbl and p85 in the complexes may contribute to the failure of R-EL4 cells to respond to phorbol ester. Phorbol Esters extracellular matrix protein 1 Mus musculus
