Scientists Have Discovered The Protein That Enables Hearing And Balance

Scientists know a lot about the human body and about the ears, but even with all of our technological advancements, it can be hard to pinpoint precise mechanisms. Have you ever wondered exactly what happens in your ear when you hear a sound? Are you curious about what keeps you on your feet and walking in a straight line? Most people know that the ears play a role in both hearing and balance, and that those with hearing loss often experience problems in balance. Recently, scientists have discovered a protein that enables hearing and balance in the ear.

A Special Protein in the Ear

Scientists at Harvard Medical School have been trying to find out exactly which cells are involved in balance and hearing, and have been looking for a protein that helps you here. They’ve recently discovered a protein called TMC1 that is able to convert sound, along with motions of the head, into electrical signals that are sent to the brain. This information allows the brain to maintain balance, and also helps you hear.

This research was published in the journal Neuron, and the discovery of this protein begins to explain the molecular mechanism that help us hear. The TMC1 protein is located on the tiny hair cells in the inner ear. These cells detect sound waves, and convert the sound waves into electrical signals that can be sent to the brain for processing. The TMC1 protein is the mechanism used by the hair cells to detect the sound waves and send signals to the brain. Scientists are elated with the discovery, since it gives great insight into how the body functions. “The search for this sensor protein has led to numerous dead ends,” says David Corey, one of the senior authors of the paper, “but we think this discovery ends the quest.”

TMC1 Found in Other Animals

The TMC1 protein has been found throughout the animal kingdom, and now that we know its role in hearing and balance, it’s easy to understand why. This protein is found in many vertebrate species, and shines a light on how important hearing and balance are for the survival of many species. The fact that this protein is found throughout the animal kingdom is proof that this is the protein scientists were looking for, and is responsible for converting sounds waves into electrical waves. Researchers are so sure that they’ve labeled this protein the “gatekeeper of hearing”.

Explaining Genetic Causes of Hearing Loss

The discovery of this protein could have implications for those born with hearing loss. 2 to 3 out of every 1,000 children in the U.S. are born with hearing loss, and understanding the TMC1 protein means that we’re closer to understanding the genetic causes of hearing loss. Mutations in this protein are one cause of hereditary hearing loss, and understanding how this protein works could be the key to treating certain forms of genetic hearing loss. Researchers are now focusing on this protein to understand how it aids in hearing and balance, and are hoping to find new treatment methods for genetic hearing loss.
