This report demonstrates that GM-CSF induces the tyrosine phosphorylation of Shc protein which is implicated in Ras activation. Three isoforms of Shc are ubiquitously phosphorylated induced by GM-CSF in TF-1, a cell line of erythroid origin. It is also shown that Shc is associated with the adaptor protein Grb2. The formation of Shc-Grb2 complex may directly link tyrosine phosphorylation events to Ras activation in TF-1 cells.

D000071425	Src Homology 2 Domain-Containing, Transforming Protein 1	An SHC-signaling adaptor protein that transduces PHOSPHOTYROSINE-dependent signals downstream of RECEPTOR PROTEIN-TYROSINE KINASES and non-receptor tyrosine kinases. It is required for TGF-BETA-induced CELL MIGRATION; NEOLPASM INVASION; and METASTASIS of BREAST NEOPLASMS; its SH2 DOMAIN is essential for tumor survival. It also functions in signaling downstream of ANGIOPOIETIN RECEPTOR TIE-2, regulating the migration of ENDOTHELIAL CELLS; and PHYSIOLOGIC NEOVASCULARIZATION.

D016178	Granulocyte-Macrophage Colony-Stimulating Factor	An acidic glycoprotein of MW 23 kDa with internal disulfide bonds. The protein is produced in response to a number of inflammatory mediators by mesenchymal cells present in the hemopoietic environment and at peripheral sites of inflammation. GM-CSF is able to stimulate the production of neutrophilic granulocytes, macrophages, and mixed granulocyte-macrophage colonies from bone marrow cells and can stimulate the formation of eosinophil colonies from fetal liver progenitor cells. GM-CSF can also stimulate some functional activities in mature granulocytes and macrophages.
