A channel linked receptor transduces functions of the same protein molecule. An example of a channel linked receptor are neurotransmitters in the brain.

The receptor type exemplified by opening a channel to let sodium into the cell is the ligand-gated ion channel. When a specific ligand, such as a neurotransmitter, binds to the receptor, it causes a conformational change that opens the channel, allowing sodium ions (Na+) to flow into the cell. This influx of sodium typically leads to depolarization of the cell membrane, which can trigger an action potential in neurons. Examples of such receptors include the nicotinic acetylcholine receptor and the glutamate receptor.
Acetylcholine (ACh) binding to an acetylcholine receptor triggers a conformational change in the receptor protein, leading to the opening of an ion channel within the receptor. This allows specific ions, such as sodium or potassium, to flow across the cell membrane, resulting in changes in membrane potential and ultimately leading to cellular responses.
Chemically-gated ion channels are receptor membrane proteins that are permeable to specific ions. The 'gating' part of it refers to the channel being open only once activated; which in this case will be by a chemical. An example would be the AMPA glutamate receptor, which has a channel pore that is permeable to sodium ions. Only by binding to glutamate (a neurotransmitter) does the channel allow sodium ions to enter the cell.

Receptor protein is coupled with an ion channel
The Transient receptor potential channel-interacting protein (TRIP) database was created in 2006. It aims to provide a comprehensive resource for protein-protein interactions involving TRP channels and TRP channel-interacting proteins.

N. Take a G protein linked receptor for an example. The ligand docks and causes a conformational change that causes a G protein to dock with the transmember protein receptor and initiate signal transduction through secondary messengers.
