A publication describing this structure is not available. The depositing authors are Tahirov, T.H.search; Inoue-Bungo, T.search; Sato, K.search; Shiina, M.search; Hamada, K.search; Ogata, K.search

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2006.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely DNA (5'-D(P*DTP*DAP*DGP*DGP*DAP*DTP*DTP*DGP*DCP*DGP*DCP*DAP*DAP*DTP*DAP*DT)-3'), DNA (5'-D(P*DAP*DAP*DTP*DAP*DTP*DTP*DGP*DCP*DGP*DCP*DAP*DAP*DTP*DCP*DCP*DT)-3'), and CCAAT/enhancer-binding protein beta.

The molecule most likely forms heterotetramers.
