Cross-linking of this lymphocyte-specific protein , designated TACI ( transmembrane activator and CAML -interactor ), on the surface of transfected Jurkat cells with TACI -specific antibodies led to activation of the transcription factors NF-AT , AP-1 , and NFkappaB .
 ( protein: TACI, None) , ( protein: transmembrane activator and CAML -interactor, None) , ( protein: AP-1, None) , ( protein: NFkappaB, None) , ( protein: lymphocyte-specific protein, None) , ( protein: transcription factors, None) , ( protein: TACI, None) , ( cell line: transfected Jurkat cells, None) , ( protein: CAML, None) , ( protein: TACI -specific antibodies, None) , ( protein: NF-AT, None)
