Crystal Structure of the human RXR alpha ligand binding domain bound to the eicosanoid DHA (Docosa Hexaenoic Acid) and a coactivator peptide

The structure was published by Egea, P.F., Mitschler, A., and Moras, D., in 2002 in a paper entitled "Molecular Recognition of Agonist Ligands by RXRs" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2002.

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

This PDB entry contains a complex of 2 biomacromolecules, namely RXR retinoid X 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.
