2p15 Summary


Crystal structure of the ER alpha ligand binding domain with the agonist ortho-trifluoromethylphenylvinyl estradiol

The structure was published by Nettles, K.W., Bruning, J.B., Gil, G., et al., Hanson, R.N., Joachimiak, A., and Greene, G.L., in 2007 in a paper entitled "Structural plasticity in the oestrogen receptor ligand-binding domain." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.94 Å and deposited in 2007.

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 GRIP peptide.

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.
