Definitions related to calcium signaling:
-
Any process that involves the local flux of calcium from the endoplasmic reticulum or sarcoplasmic reticulum to the cytosol. This process is involved in intracellular signaling and in maintaining depolarization of the heart.NCI ThesaurusU.S. National Cancer Institute, 2021
-
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, sparks, or puffs. The calcium acts as an intracellular messenger by activating calcium-responsive proteins.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
(calcium-mediated signaling) Any intracellular signal transduction in which the signal is passed on within the cell via calcium ions.Gene Ontology DictionaryGene Ontology Consortium, 2021
