Opposite regulation of gene transcription and cell proliferation by c-Myc and Max.


c-Myc and Max are nuclear phosphoproteins capable of forming DNA-binding, homo- and heteropolymeric complexes in vitro and in vivo. Using a transient cotransfection assay involving c-Myc and Max expression vectors and a reporter gene plasmid containing the Myc/Max binding site, we find that Max represses transcription, whereas a significant stimulation is… (More)
