Secondary messenger system
WebSecond messengers are small, non-protein molecules or ions that transmit a signal that has been generated when the ligand binds to the cell-surface receptor. Second messengers … Web4 Dec 2024 · IP3 is a second messenger molecule utilized in signal transduction in biological cells together with diacylglycerol (DAG). IP3 is soluble and diffuses into the cell, where it interacts with its receptor, a calcium channel found in the endoplasmic reticulum, whereas DAG remains inside the membrane.
