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. WebWhat is the IP3 pathway? IP3 pathway: IP3 acts to release Ca2+ from the endoplasmic reticulum by binding to receptors that are ligand-gated Ca2+ channels. As a result, cytosolic Ca2+ levels increase to about 1 M, which affects the activities of a variety of target proteins, including protein kinases and phosphatases.
