The membrane structure of inner ear protein prestin is revealed

“As mammals, we have very sensitive hearing, thanks to a process known as cochlear amplification. This amplification is down to sensory cells in the inner ear called outer hair cells (OHCs), and it is thought to depend on the way a protein called prestin—found in the OHC membrane—responds to changes in electric potential. However, the membrane structure of prestin is unknown, so a team including a researcher from Kanazawa University has used force spectroscopy to determine it. Their findings are published in the Journal of Biomechanical Science and Engineering.” -from this current article, as I constantly point out, you may see, all fields of knowledge are interspersed and multidisciplinary.
