WebIP3 (inositol triphosphate) increases free cytosolic Ca2+ by releasing Ca2+ from intracellular compartments. IP3 is an endogenous ligand for calcium ligand-gated channels imbedded in the endoplasmic and sarcoplasmic reticulum in smooth and skeletal muscle, respectively. Upon binding, IP3 opens the channel to release free calcium into the cytosol. Human IP3's main functions are to mobilize Ca from storage organelles and to regulate cell proliferation and other cellular reactions that require free calcium. In smooth muscle cells, for example, an increase in concentration of cytoplasmic Ca results in the contraction of the muscle cell. In the nervous … Meer weergeven Inositol trisphosphate or inositol 1,4,5-trisphosphate abbreviated InsP3 or Ins3P or IP3 is an inositol phosphate signaling molecule.
