These findings support a model in which gamma(c) serves primarily to activate signal transduction by the IL-7R complex , while IL-7R alpha determines specific signaling events through its association with cytoplasmic signaling molecules .
 ( protein: cytoplasmic signaling molecules, None) , ( protein: gamma(c), None) , ( protein: IL-7R alpha, None) , ( protein: IL-7R complex, None)
