- signal transduction
- listen (SIG-nul tranz-DUK-shun)
- The process by which a cell responds to substances in its environment. The binding of a substance to a molecule on the surface of a cell causes signals to be passed from one molecule to another inside the cell. These signals can affect many functions of the cell, including cell division and cell death. Cells that have permanent changes in signal transduction molecules may develop into cancer.
