Signal Transduction

Signal transduction is a biological process that describes how a signal on the cell surface is converted into an appropriate cellular response. This process involves the transmission of a signal through a chain of molecules, usually proteins, to a final effector molecule that responds to the signal by producing a cellular response. Signal transduction pathways are important for allowing cells to respond to their environment and control their growth, development, and other functions. They are particularly important in areas such as development, immunity, and cancer.
