1 In the present study we evaluated tyrosine phosphorylation of c-Cbl and the interaction of the Grb2/c-Cbl complex with signaling proteins upon activation of non-tyrosine (c-Mpl) and tyrosine kinase (c-Kit) receptors leading to myeloid cell proliferation. Tyrosine Cbl proto-oncogene Homo sapiens
2 In the present study we evaluated tyrosine phosphorylation of c-Cbl and the interaction of the Grb2/c-Cbl complex with signaling proteins upon activation of non-tyrosine (c-Mpl) and tyrosine kinase (c-Kit) receptors leading to myeloid cell proliferation. Tyrosine Cbl proto-oncogene Homo sapiens
3 By using the growth factor dependent M-07e cell line, we found that both c-Mpl and c-Kit ligands, namely: SCF and TPO, induce c-Cbl tyrosine phosphorylation. Tyrosine Cbl proto-oncogene Homo sapiens
4 Taken together our results demonstrate that c-Cbl plays an important role in coupling both tyrosine and non-tyrosine kinase receptors to downstream effector molecules and that different signaling molecules interact with Grb2/c-Cbl complex when non-tyrosine or tyrosine kinase receptors are activated. Tyrosine Cbl proto-oncogene Homo sapiens
