摘要: Ca2+ is well established as an intracellular second messenger. However, the molecular identification of a detector for extracellular — calcium-sensing receptor has opened up possibility that might also function messenger outside cells. Information about local concentration conveyed to interior many cell types through this unique G-protein-coupled receptor. Here, we describe new emerging concepts concerning signalling Ca2+, with particular emphasis on
