Combinatorial regulation of eukaryotic transcription is mediated by proteins that associate in a specific manner to form multiprotein DNA-bound complexes. Substantial progress has recently been made towards the understanding of the molecular determinants of the protein-protein and protein-DNA interactions that govern assembly of these complexes. Three-dimensional structures have been determined of the MATalpha2/MCM1-DNA complex, the p50/p65 Rel homology domain heterodimer bound to DNA, the NFAT/Fos-Jun/DNA quaternary complex, and of the GABPalpha/beta ETS domain-ankyrin repeat heterodimer bound to DNA.
