	Work Report
		Calcium is thought to be involved in the pathogenetic mechanisms of amoebiasis.
		This monomeric protein shows homology with many calcium binding proteins only in the calcium binding loops and not in the inter-loop regions which are suspected to be the sites that interact with other proteins.
		ANS binding data shows the solvation of myristoyl group in the presence of Ca, which might be due to the presence of a Ca -myristoyl switch.

	GBP Binding Selectivity
		This trend was absent in the case of the binding protein where each of the three ions was invariably coordinated by eight oxygen atoms, with the averaged values being 7.9 for Mg++, 7.9 for Ca++, and 8.0 for Ba++.
		To isolate the source of this electrostatic strain in the protein, a further decomposition of the average Ca++-Mg++ difference in nonbonded interaction energy in the inner and outer coordinating shells (reflecting the eight coordinating oxygen atoms versus the rest of the protein) was performed (figure 7), again using the non-perturbation dynamics trajectories.
		The Mg++-induced protein strain (relative to Ca++-ligated) is subdivided into three ensemble average Ca++-Mg++ difference components: the nonbonded interaction energy of the inner shell of eight oxygens (left), that of the protein (center), and that between the inner shell and the rest of the protein (right).

		Ionic calcium (Ca) is a well-established intracellular messenger important in coupling excitation to contraction in muscle, excitation to transmitter release in nerves, and secretagogue action to secretion in various exocrine and endocrine glands.
		A rise in cytoplasmic calcium can be brought about either by opening of calcium channels in the membrane or by release of calcium from intracellular stores such as from endoplasmic reticulum.
		In the liver, where calcium mediates the action of a number of hormones (e.g., epinephrine, vasopressin, angiotensin), several proteins are phosphorylated following exposure to these hormones.

	Calcium-binding protein - Wikipedia, the free encyclopedia
		Calcium-binding proteins are proteins that participate in calcium cell signalling pathways by binding to Ca The most ubiquitous Ca -sensing protein, found in all eukaryotic organisms including yeasts, is calmodulin.
		Intracellular storage and release of Ca from the sarcoplasmic reticulum is associated with the high-capacity, low-affinity calcium-binding protein, calsequestrin (Siegel, 1999).
		With their role in signal transduction, calcium-binding proteins contribute to all aspects of the cell's functioning, from homeostasis to learning and memory.

	Calcium binding protein
		While it is well established that the guanylate cyclase is activated by small acidic Ca -binding proteins named guanylate cyclase-activating proteins (GCAPs) at low free Ca concentration, recent findings suggest that the guanylate cyclase is also activated at high Ca concentration by the Ca -sensor protein S100β.
		This activation pathway is localized in the photoreceptor-bipolar synapse and, therefore, does not interfere with the regulation of guanylate cyclase by GCAPs in the outer segment of the photoreceptor cell.
		The Ca -sensor proteins S100β and GCAPs bind to different sites that are located in distant regions of the guanylate cyclase.
