We have recently discovered that CCAAAT / enhancer - binding protein - beta ( C / EBP - beta ) induces gene transcription through a novel IFN response element called the gamma - IFN - activated transcriptional element
 GENE: CCAAAT / enhancer - binding protein - beta; GENE: C / EBP - beta; GENE: IFN response element
