The nuclear receptor LRH-1 discriminates between ligands using distinct allosteric signaling circuits
Nuclear receptors (NRs) use distinct signaling pathways to communicate ligand information to the activation function surface (AFS). Understanding these allosteric networks in liver receptor homolog-1 (LRH-1) can guide therapeutic development.
Area of Science:
- Molecular Biology
- Biochemistry
- Structural Biology
Background:
- Nuclear receptors (NRs) are ligand-activated transcription factors crucial for biological regulation.
- NR function relies on ligand-induced conformational changes to recruit coregulators to the activation function surface (AFS).
- The precise mechanisms of allosteric communication between the ligand-binding pocket and the AFS remain poorly understood.
Conclusions:
- Novel insights into LRH-1 allosteric signaling and coregulator interactions were uncovered.
- The findings reveal how different ligands modulate LRH-1 activity through distinct communication pathways.
- This quantitative simulation approach provides a framework for studying allosteric signaling in other receptors and developing targeted therapeutics.
