Calcium Wave Definition

Advertisement

Calcium Wave: Signal transduction mechanisms whereby calcium mobilization (from outside the cell or from intracellular storage pools) to the cytoplasm is triggered by external stimuli. Calcium signals are often seen to propagate as waves, oscillations, spikes or puffs. The calcium acts as an intracellular messenger by activating calcium-responsive proteins.

Synonym: calcium spike, calcium signaling, calcium puff, calcium oscillation.
