Finding molecules that activate GPR156, a receptor tied to hearing and balance

Discovery of synthetic and endogenous ligands for orphan GPCR GPR156

NIH-funded research University of Rochester · NIH-11170727

This project looks for natural and lab-made molecules that switch on GPR156, a protein linked to hearing and balance, to help develop new treatments for ear and balance problems.

What this research studies

Researchers use sensitive cell-based tests that report when GPR156 is active to screen large libraries of candidate compounds. They will look for natural ligands present in brain tissue and apply proximity-labeling and proteomics to identify proteins that bind GPR156. Promising molecules and interacting proteins will be validated in physiologically relevant systems to confirm effects on signaling pathways related to hearing and balance. The goal is to create therapeutic leads that could move into animal testing and, eventually, human trials.

Who could benefit from this research

Good fit: People with hearing loss, vestibular (balance) disorders, or related inner ear or neurological conditions could be among those who might benefit from therapies developed from this research.

Not a fit: Patients with health issues unrelated to hearing or balance are unlikely to receive direct benefit from this project.

Why it matters

Potential benefit: If successful, this work could produce new drug leads or biological targets for treating hearing loss and balance disorders.

How similar studies have performed: Related screening and ligand-discovery approaches have identified ligands for some orphan GPCRs, but finding functional ligands and partners for GPR156 remains largely novel.
