Geneticists have found a protein that is responsible for the sensitivity to touch

Scientists have found a protein responsible in the body of all mammals for tactile sensations, says Zee News. The connection is in the ion channels of the cells and enables you to feel the touch.

To prove their theory, the scientists conducted an experiment with laboratory mice. Animals have deleted gene Piezo2. In the mouse has lost sensitivity, however, the pain continued to feel.

"We found that the gene Piezo2 helps mammals to sense touch. In mice without this gene sensitivity to light touch significantly reduced," according to Ardem Patapoutian (research Institute of SCRIPPS).

Scientists suggest that the gene Piezo2 is responsible for the sensation of light touch. The pain is more complex physiological reaction, so it cannot be turned off, driving a single gene.
