A second messenger is a small, nonprotein, water-soluble molecule or ion, such as a calcium ion (Ca2+) or cyclic AMP, that relays a signal to a cell’s interior in response to a signaling molecule bound by a signal receptor protein.
Um segundo mensageiro é uma molécula ou íon pequeno, não proteico e solúvel em água, como um íon cálcio (Ca2+) ou AMP cíclico, que transmite um sinal para o interior de uma célula em resposta a uma molécula sinalizadora ligada por uma proteína receptora de sinal.
