Crystal structure of the ligand binding domain of the Vitamin D nuclear receptor in complex with Gemini and a coactivator peptide

Overview

The crystal structure of the ligand binding domain (LBD) of the wild-type, Vitamin D receptor (VDR) of zebrafish bound to Gemini, a synthetic agonist, ligand with two identical side chains branching at carbon 20 reveals a, ligand-dependent structural rearrangement of the ligand binding pocket, (LBP). The rotation of a Leu side chain opens the access to a channel that, can accommodate the second side chain of the ligand. The 25% increase of, the LBP's volume does not alter the essential agonist features of VDR. The, possibility to adapt the LBP to novel ligands with different chemistry, and/or structure opens new perspectives in the design of more specifically, targeted ligands.

About this Structure
