For example, binding DNA activity with the oncogenes / transcription factors MAFK (V-Maf Avian Musculoaponeurotic Fibrosarcoma Oncogene Homolog K), RAD21 (RAD21 Cohesin Complex Component), JUND (Jun D Proto-Oncogene), and CEBPB (CCAAT/Enhancer Binding Protein Beta, also known as liver activator protein) has been reported in hepatocellular carcinoma and liver-derived line cells (data extracted from http://www.geneprof.org/). The gene discussed is MAFK; the disease is hepatocellular carcinoma.
