Protein Daple coordinates single-cell and organ-wide directionality in the inner ear

Sensory hair cells in the inner ear combine into hair bundles to convert sound waves into electrical signals. Both single-cell and organ-wide directionality are critical for hearing, but these two levels of organization are controlled by largely distinct molecular mechanisms during inner ear development. Researchers have identified a protein, Daple, that interacts with both systems and is a promising candidate to coordinate single cell and organ-wide directionality.
