The increased intracellular Ca2+ions bind to a vesicle-associated protein (synaptotagmin) which favors association of a second vesicle protein (synaptobrevin) with one or more proteins in the plasma membrane of the nerve terminal. Like other transmembrane receptors, acetylcholine receptors are classified according to their "pharmacology," or according to their relative affinities and sensitivities to different molecules. Although all acetylcholine receptors, by definition, respond to acetylcholine, they respond to other molecules as well. • Nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) a… bipolar 1 with psychotic features dsm 5
