1oy3 Summary



The structure was published by Malek, S., Huang, D.B., Huxford, T., Ghosh, S., and Ghosh, G., in 2003 in a paper entitled "X-ray crystal structure of an IkappaBbeta x NF-kappaB p65 homodimer complex." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.05 Å and deposited in 2003.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Transcription factor p65 and transcription factor inhibitor I-kappa-B-beta.
