Here we report that overexpression of Syk in the Lck -negative JCaM1 cells enabled the T cell antigen receptor /CD3 complex to induce a normal activation of the mitogen-activated protein kinase ( MAPK ) pathway and expression of a nuclear factor of activated T cells reporter construct.
 ( protein: Lck, None) , ( protein: nuclear factor of activated T cells, None) , ( cell type: T cells, None) , ( protein: T cell antigen receptor /CD3 complex, None) , ( protein: T cell antigen receptor, None) , ( cell line: Lck -negative JCaM1 cells, None) , ( protein: MAPK, None) , ( protein: Syk, None) , ( protein: mitogen-activated protein kinase, None)
