Human estrogen receptor alpha ligand-binding domain in complex with 2-(but-1-enyl)-17beta-estradiol and a glucocorticoid receptor interacting protein 1 NR BOX II Peptide

A publication describing this structure is not available. The depositing authors are Rajan, S.S.search; Hsieh, R.W.search; Sharma, S.K.search; Greene, G.L.search

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2006.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Estrogen receptor and Nuclear receptor coactivator 2.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotetramers.
