CRYSTAL STRUCTURE OF TERNARY PROTEIN-DNA COMPLEX2
Overview
c-Myb, but not avian myeloblastosis virus (AMV) v-Myb, cooperates with, C/EBP beta to regulate transcription of myeloid-specific genes. To assess, the structural basis for that difference, we determined the crystal, structures of complexes comprised of the c-Myb or AMV v-Myb DNA-binding, domain (DBD), the C/EBP beta DBD, and a promoter DNA fragment. Within the, c-Myb complex, a DNA-bound C/EBP beta interacts with R2 of c-Myb bound to, a different DNA fragment; point mutations in v-Myb R2 eliminate such, interaction within the v-Myb complex. GST pull-down assays, luciferase, trans-activation assays, and atomic force microscopy confirmed that the, interaction of c-Myb and C/EBP beta observed in crystal mimics their long, range interaction on the promoter, which is accompanied by intervening DNA, looping.
