cGMP (cyclic guanosine monophosphate)

Cyclic guanosine monophosphate (cGMP) is a small molecule found in cells that acts as a signaling messenger, helping cells respond to various signals. When a signaling molecule binds to a receptor on the cell surface, it often triggers the production of cGMP inside the cell. This molecule then activates specific proteins that regulate functions such as blood vessel dilation, sensory perception, and cell growth. Essentially, cGMP helps translate external signals into internal actions, playing a vital role in processes like maintaining blood pressure and visual signaling.
