Calcium signaling resulting from depolarization of neurons can trigger changes in transcription, and this response has been called excitation-transcription (E-T) coupling. In neurons, voltage-gated and ligand-gated calcium-permeable channels contribute to the increase in intracellular calcium. It appears that calcium signals mediated by specific voltage-gated calcium channels may have distinct roles in E-T coupling.
