Structural investigation of the ligand binding domain of the zebrafish VDR in complexes with 1alpha,25(OH)2D3 and Gemini: purification, crystallization and preliminary X-ray diffraction analysis

J Steroid Biochem Mol Biol. 2004 May;89-90(1-5):55-9. doi: 10.1016/j.jsbmb.2004.03.109.


The nuclear receptor of Vitamin D can be activated by a large number of agonist molecules with a wide spectrum in their stereochemical framework. Up to now most of our structural information related to the protein-ligand complex formation is based on an engineered ligand binding domain (LBD) of the human receptor. We now have extended our database, using a wild-type LBD from zebrafish that confirms the previously reported results and allows to investigate the binding of ligands that induce significant conformational changes at the protein level.
