Fly Protein Tunes In To Water

Ion channel in fruit flies' taste neurons hints at how more advanced animals sense water
Department: Science & Technology
Keywords: ion channel, taste

A newly discovered ion channel protein that helps fruit flies sense water could help further understanding of how animals regulate water intake, an essential process for life. Insects and some mammals have water-responsive taste cells, and certain ion channels can respond to changes in solute concentrations, but the molecular basis of water detection by animals is still not clear.
