Lysosomes receive calcium through close association with the ER and IP3 receptors
Free calcium in the cytosol is critical for regulating cellular processes in response to intracellular and extracellular stimuli. Calcium signaling involves the opening of calcium channels within the plasma membrane or membranes of intracellular organelles, most notably the endoplasmic reticulum (ER). Extracellular stimuli lead to the release of calcium from the ER in response to
