Web27 sep. 2024 · Receptors like ionotropic receptors comprise individual protein subunits that make up an ion channel’s pores. The ionotropic receptors are linked directly to ion channels and contain functional domains, which include an extracellular site that binds neurotransmitters and a membrane domain that forms an ion channel.

Web20 okt. 2024 · Downstream mechanism. When a ligand binds to ion-channel linked receptors, the extracellular domain of the receptor undergoes changes in its conformation, opening a channel across the plasma membrane. This allows specific ions (such as Na+, Ca2+, H+, and Mg2+, etc.) or other key molecules to pass through the open channel.
