We conclude that the MAP kinase signal transduction pathway consisting of Raf-1 , MEK1 , and ERK1 and ERK2 functions in the stimulation IL-2 gene transcription in activated T lymphocytes .
 ( protein: IL-2, None) , ( protein: Raf-1, None) , ( protein: ERK1, None) , ( protein: MAP kinase, None) , ( cell type: T lymphocytes, None) , ( protein: ERK2, None) , ( protein: MEK1, None) , ( DNA: IL-2 gene, None)
