Receptor binding site
Webb11 apr. 2024 · Upon agonist binding to the orthosteric binding site, the conformational change of the receptor prompts the activation of intracellular G proteins. Subsequently, the Gαi and Gβγ subunits dissociate from each other and then act on various downstream intracellular signaling pathways [ 17 , 19 , 20 , 22 ].

Webb1 aug. 1998 · Nicotinic acetylcholine receptors (AChRs) are activated by ACh binding to two sites located on different α subunits. The two α subunits, αγ and αδ, are distinguished by their interface with γ and δ subunits. We have characterized the formation of the ACh binding sites and found, contrary to the current model, that the sites form at different …
WebbClassically, NMDA receptor NR2 subunits associate with PSD-95 MAGUKs via a conserved ES(E/D)V amino acid sequence located at their C termini.
