A Chemical, Genetic, and Structural Analysis of the nuclear bile acid receptor FXR

The structure was published by Downes, M., Verdecia, M.A., Roecker, A.J., et al., Noel, J.P., Nicolaou, K.C., and Evans, R.M., in 2003 in a paper entitled "A chemical, genetic, and structural analysis of the nuclear bile acid receptor FXR" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2003.

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

The PDB entry contains the structure of Bile acid receptor. This molecule has the UniProt identifier Q96RI1 (NR1H4_HUMAN)search. The sample contained 232 residues which is < 90% of the natural sequence. Out of 232 residues 216 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 is most likely monomeric.
