Cell Signaling presents the mechanisms and molecular components that allow cells to process information and respond to their environment. It provides undergraduate and graduate students the conceptual tools needed to make sense of the dizzying array of pathways used by the cell to communicate. By emphasizing the common design principles and logic that drive all signaling, the book develops a conceptual framework through which students can understand how myriad signaling molecules interact with each other in vast interconnected networks. Many specific examples are provided throughout to illustrate common principles, and provide a comprehensive overview of major eukaryotic signaling pathways.

Calcium ions (Ca2+) impact nearly every aspect of cellular life. This review examines the principles of Ca2+ signaling, from changes in protein conformations driven by Ca2+ to the mechanisms that control Ca2+ levels in the cytoplasm and organelles. Also discussed is the highly localized nature of Ca2+-mediated signal transduction and its specific roles in excitability, exocytosis, motility Overview of cell signaling - YouTube
