Granzyme B gene transcription is induced in activated lymphocytes upon antigenic stimulation , and several regulatory regions including CBF , AP-1 , and Ikaros binding sites have been shown to be essential in the control of granzyme B promoter activation .
 ( protein: CBF, None) , ( DNA: granzyme B promoter, None) , ( protein: AP-1, None) , ( DNA: Ikaros binding sites, None) , ( DNA: regulatory regions, None) , ( cell type: lymphocytes, None) , ( protein: Ikaros, None)
