WebCalcium ion (Ca2+) is a ubiquitous intracellular messenger and changes in its concentration impact on nearly every aspect of cell life. Endoplasmic reticulum (ER) represents the major intracellular Ca2+ store and the free Ca2+ concentration ([Ca2+]) within its lumen ([Ca2+]ER) can reach levels higher than 1 mM. Several genetically-encoded ER-targeted … WebTight interactions, also called high affinity interactions, have a low K d value. The K d is often used to compare affinities because it intuitively gives an idea of the concentration needed to reach saturation of the interaction: it describes the concentration of ligand at which half of the target molecules are bound to ligand molecules.
