Calcium Controls Gene Expression via Three Distinct

Calcium ions are the principal second messenger in the control of gene expression by electrical activation of neurons. However, the full complexity of calcium-signaling pathways leading to transcriptional activation and the cellular machinery involved are not known. Using the c- fos gene as a model system, we show here that the activity of its complex promoter is controlled by three
