We have previously shown that the membrane-proximal portion in the cytoplasmic domain of the human IL-4R alpha ( hIL-4R alpha ) is critical for proliferation, generation of germline epsilon transcript, and activation of STAT6 , based on analyses of truncated hIL-4R alphas .
 ( protein: STAT6, None) , ( protein: IL-4R alpha, None) , ( protein: membrane-proximal portion, None) , ( protein: human IL-4R alpha, None) , ( protein: cytoplasmic domain, None) , ( protein: hIL-4R alpha, None) , ( protein: truncated hIL-4R alphas, None)
