Parasite calcium homeostasis

Parasite calcium homeostasis" is not a specific molecule or receptor but a term referring to the collective set of proteins, pumps, transporters, and signaling pathways that regulate intracellular calcium (Ca2+) levels in parasitic organisms such as *Plasmodium* spp. (malaria), *Toxoplasma gondii*, and *Trypanosoma* spp. Calcium is essential for numerous processes in these parasites, including motility, secretion, invasion, egress, and stage differentiation[1][2][3][4][5]. Key molecular components include Ca2+-ATPases (e.g., SERCA, PMCA), acidocalcisomes, plant-like vacuoles, ER calcium channels, Ca2+ binding proteins (calmodulin, CDPKs), and, in some species, TPC homologs (calcium-permeable channels)[1][2][4][5][6][7]. While some anti-parasitic drugs (notably artemisinin and thapsigargin) target or disrupt parasite calcium regulation, "parasite calcium homeostasis" itself is a process or physiological phenomenon, not a discrete drug target such as an individual enzyme or receptor. For structure-based or molecularly precise pharmacological workflows, specific components like "calcium ATPase, SERCA type" or "calcium-dependent protein kinase 1" are considered direct targets, not the overall homeostasis pathway[3][6][8]. **In summary:** - The entry "Parasite calcium homeostasis" is **not a canonical single molecular target** or receptor: it is a physiological process involving many components, and should not be used as a target name for structured databases. - For structured information, refer to specific molecules or protein targets within this system (e.g., "Plasmodium falciparum calcium ATPase (PfSERCA)" or "Toxoplasma gondii Ca2+-ATPase (TgA1)")[1][3][4][6]. **This entry is best marked as incorrect or insufficiently specific for a molecular target field.**
