PDB entry 3ert (supersedes 2ert)

HUMAN ESTROGEN RECEPTOR ALPHA LIGAND-BINDING DOMAIN IN COMPLEX WITH 4-HYDROXYTAMOXIFEN

The structure was published by Shiau, A.K., Barstad, D., Loria, P.M., et al., Kushner, P.J., Agard, D.A., and Greene, G.L., in 1998 in a paper entitled "The structural basis of estrogen receptor/coactivator recognition and the antagonism of this interaction by tamoxifen." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 1999.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of PROTEIN (ESTROGEN RECEPTOR ALPHA). This molecule has the UniProt identifier P03372 (ESR1_HUMAN)search. The sample contained 261 residues which is < 90% of the natural sequence. Out of 261 residues 242 were observed and are deposited in the PDB.

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 homodimers.
