WebOct 5, 2024 · The P2RX2 gene encodes the P2X2 receptor, which assembles as a trimer to form a ligand-gated ion channel gated by extracellular ATP. P2X2 receptors mediate …

The ionotropic glutamate receptors bind the neurotransmitter glutamate. They form tetramers with each subunit consisting of an extracellular amino terminal domain (ATD, which is involved tetramer assembly), an extracellular ligand binding domain (LBD, which binds glutamate), and a transmembrane domain (TMD, which forms the ion channel). The transmembrane domain of each sub… WebJan 3, 2024 · When neurotransmitters bind to their receptors, ion channels in responding neuron or muscle cells open. The resulting influx of Na + ions disrupts the resting potential of the target cell. The effect is only transient if the membrane potential remains negative. However, if enough Na+ ions enter the cell, the membrane becomes depolarized.
