  A Structure-Guided Approach to an Orthogonal Estrogen-Receptor-Based Gene Switch Activated by Ligands Suitable for in Vivo Studies

  摘要：

  A strategy to obtain a fully orthogonal estrogen-receptor-based gene switch responsive to molecules with acceptable pharmacological properties is presented. From a series of tetrahydrofluorenones active on the wild-type estrogen receptor (ER) an inactive analogue is chosen as a new lead compound. Coevolution of receptor mutants and ligands leads to an ER-based gene switch suitable for studies in animal models.

  The present invention relates to an orthogonal gene switch for regulating the expression of a desired gene. The gene switch comprises a chimeric transcription factor that does not respond to endogenous ligands, and a ligand that is capable of activating the chimeric transcription factor but not endogenous transcription factors. The present invention also relates to the method of constructing the orthogonal gene switch.

  Methods to rapidly and reversibly perturb the functions of specific proteins are desirable tools for studies of complex biological processes. We have demonstrated an experimental strategy to regulate the intracellular concentration of any protein of interest by using an engineered destabilizing protein domain and a cell-permeable small molecule. Destabilizing domains have general utility to confer instability to a wide range of proteins including integral transmembrane proteins. This study reports a destabilizing domain system based on the ligand binding domain of the estrogen receptor that can be regulated by one of two synthetic ligands, CMP8 or 4-hydroxytamoxifen.
