"WebThe IP3R is an IP3-sensitive Ca 2+ channel localized to the smooth endoplasmic reticulum (SER). Activation of group 1 mGluRs by glutamate results in production of the second messenger IP3. IP3 then binds to the IP3R, causing it to open and release Ca 2+ from the SER, which functions as an intracellular calcium store. " - Ip3r agonist carbachol
