We show that ligand-induced homodimerization of chimeric surface receptors consisting of the extracellular and transmembrane domains of the erythropoietin receptor and of the intracellular domain of IL-4Ralpha induces Janus kinase 1 ( Jak1 ) activation , STAT6 activation , and Cepsilon germline transcripts in human B cell line BJAB .
 ( protein: erythropoietin receptor, None) , ( protein: intracellular domain, None) , ( protein: Jak1, None) , ( cell line: human B cell line BJAB, None) , ( protein: STAT6, None) , ( protein: Janus kinase 1, None) , ( RNA: Cepsilon germline transcripts, None) , ( protein: IL-4Ralpha, None) , ( protein: chimeric surface receptors, None)
