... or the Na + /H + exchanger which regulates intracellular pH. The inositol trisphosphate (Ins l,4,5P 3 ) released to the cytosol functions as a second messenger to release calcium from the endoplasmic reticulum. The Ins 1,4,5P 3 acts on a specific receptor to enhance the passive efflux of calcium while...
