This poster highlights some of the key roles of calcium ions in the calcium signaling pathway.
Calcium pathway – an overview
Calcium ions play a role in cell excitability, exocytosis, motility, apoptosis, and transcription. Calcium enters the cytoplasm from intracellular stores or from extracellular space, which is driven by a large electrochemical gradient across the plasma membrane.
Calcium can act directly from the activation of ion channels causing signal transduction. It can also act as a second messenger from signal transduction pathways coming from external receptors such as G-protein coupled receptors.
What to expect
Our poster covers calcium movement into and out of the cell and mitochondria. It also covers calcium activation, signal transduction and its role as a second messenger from G-protein coupled receptors.
