Receptor Structures and Receptor Families(1983–1990)
This chapter discusses two major classes of receptor function and structure: oligomeric subunits surrounding an ion-conducting pore formed a ligand-gated ion channel that opened when neurotransmitters filled the binding sites and monomeric proteins with seven transmembrane segments formed receptors that activated a coupled G-protein. With the first class, chemical signals or neurotransmitters were converted into electrical signals. With the second, chemical signals were converted to different chemical signals: G-proteins that then interacted with various enzymes and channels to elicit both chemical and electrical responses.
Keywords: receptor, oligomeric subunits, monomeric protein, chemical signals, neurotransmitters, electrical signals
