CRYSTAL STRUCTURE OF THE HUMAN TRANSCRIPTION COFACTOR PC4 IN COMPLEX WITH SINGLE-STRANDED DNA
Overview
The 1.74-A crystal structure of the human transcription cofactor PC4 in complex with a single-stranded 20-mer oligonucleotide reveals how symmetry-related beta-surfaces of the protein homodimer interact with juxtaposed 5-nucleotide DNA regions running in opposite directions. The structure explains high-affinity binding of PC4 to the complementary strands of unwinding duplex DNA, and it suggests the cofactor may have a role in relaxing negative supercoils or exposing unpaired bases for sequence-specific recognition by other biomolecules.
