Granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) are hematopoietic growth factors which stimulate the proliferation and differentiation of myeloid progenitor cells. There is a considerable degree of overlap in target cell specificity and the functional effects of GM-CSF and IL-3. GM-CSF and IL-3 induce a nearly identical pattern of protein-tyrosine phosphorylation in certain cell lines, although their receptors have no kinase domains. Furthermore, their receptor complexes share one subunit (designated as beta). These observations raise the possibility that GM-CSF and IL-3 have a common signaling pathway. Here we show that both GM-CSF and IL-3 induce tyrosine phosphorylation and kinase activity of the c-fps/fes proto-oncogene product (p92c-fes), a non-receptor protein-tyrosine kinase, in a human erythro-leukemia cell line, TF-1, which requires GM-CSF or IL-3 for growth. In addition, GM-CSF induces physical association between p92c-fes and the beta chain of the GM-CSF receptor. p92c-fes is therefore a possible signal transducer of several hematopoietic growth factors including GM-CSF and IL-3 through the common beta chain.
