To test this latter possibility, a chimeric receptor containing the extracellular domain of c-kit (the stem cell factor (SCF) receptor ) and the cytoplasmic and transmembrane domains of the IL-4R alpha chain was generated.
 ( protein: chimeric receptor, None) , ( protein: IL-4R alpha chain, None) , ( protein: extracellular domain, None) , ( protein: IL-4R, None) , ( protein: c-kit, None) , ( protein: stem cell factor (SCF) receptor, None)
