Phospholipase C cleaving PIP2 into IP3 and DAG. Specific signals can trigger a sudden increase in the cytoplasmic Ca 2+ levels to 500–1,000 nM by opening channels in the ER or the plasma membrane. The most common signaling pathway that increases cytoplasmic calcium concentration is the phospholipase C (PLC) pathway.
Inositol trisphosphate receptor (InsP3R) is a membrane glycoprotein complex acting as a Ca 2+ channel activated by inositol trisphosphate (InsP3). InsP3R is very diverse among organisms, and is necessary for the control of cellular and physiological processes including cell division, cell proliferation, apoptosis, fertilization, development, behavior, learning and memory.

Inositol trisphosphate or inositol 1,4,5-trisphosphate abbreviated InsP 3 or Ins3P or IP 3 is an inositol phosphate signaling molecule. It is made by hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP 2), a phospholipid that is located in the plasma membrane, by phospholipase C (PLC).
A common mechanism by which such cytoplasmic calcium signals are generated involves receptors that are coupled to the activation of phospholipase C. Phospholipase C generates inositol 1,4,5-trisphosphate (IP3), which in turn mediates the discharge of Ca 2+ from intracellular stores (components of the endoplasmic reticulum), allowing calcium to ...

Principle of calcium encoding.A schematics of intracellular calcium signaling and its equivalent from a calcium encoding perspective.. Calcium encoding (also referred to as Ca 2+ encoding or calcium information processing) is an intracellular signaling pathway used by many cells to transfer, process and encode external information detected by the cell.
The class of Chromadorea also utilizes the enzyme phospholipase C to regulate the releases of calcium. The enzyme releases inositol 1,4,5-trisphosphate (IP3) that denotes a signaling pathway involved in activating ovulation, the propelling of the oocyte into the spermatheca. This gene is involved in various activities like controlling GTPase ...
The IP3 is especially important for calcium influx because it binds to a IP3 receptor located in the membrane of the endoplasmic reticulum (ER). This causes a short sharp increase in calcium concentration in cytosol as the ions leave the ER through the IP3 receptor. [4] [6] However, this is not enough to activate NFAT signalling.
