Upon the introduction of the normal RAR ligand, all-trans-retinoic acid, the chimeric receptor undergoes nuclear translocation. 3. Results: Translocation Tracking
Are you looking to focus on the of RAR or the technical design of the chimera? Hem#265 rar
The translocation from cytoplasm to nucleus is observable in living cells, allowing for kinetic studies. Upon the introduction of the normal RAR ligand,
Nuclear receptors, such as the Retinoic Acid Receptor (RAR), are critical in gene regulation but often difficult to monitor in real-time within living cells. This paper explores the development of a GR-RAR chimeric protein, which fuses the nuclear/cytoplasmic translocation properties of the Glucocorticoid Receptor (GR) with the ligand responsiveness of RAR. This chimeric receptor provides a robust, in vivo, real-time translocation assay to detect physiological concentrations of RAR ligands, providing a powerful tool for ligand identification and subcellular trafficking analysis. 1. Introduction The translocation from cytoplasm to nucleus is observable
The chimeric receptor provides a dramatic and easily monitored visual indicator of RAR ligand presence in the cellular environment.
