>PF02932 Neur_chan_memb: Neurotransmitter-gated ion-channel transmembrane region ion channel family signature gamma-aminobutyric acid (GABA) receptor signature nicotinic acetylcholine receptor signature; InterPro: IPR006029 Neurotransmitter ligand-gated ion channels are transmembrane receptor-ion channel complexes that open transiently upon binding of specific ligands, allowing rapid transmission of signals at chemical synapses [, ]
Five of these ion channel receptor families have been shown to form a sequence-related superfamily: Nicotinic acetylcholine receptor (AchR), an excitatory cation channel in vertebrates and invertebrates; in vertebrate motor endplates it is composed of alpha, beta, gamma and delta/epsilon subunits; in neurons it is composed of alpha and non-alpha (or beta) subunits []. Glycine receptor, an inhibitory chloride ion channel composed of alpha and beta subunits []. Gamma-aminobutyric acid (GABA) receptor, an inhibitory chloride ion channel; at least four types of subunits (alpha, beta, gamma and delta) are known []. Serotonin 5HT3 receptor, of which there are seven major types (5HT3-5HT7) []. Glutamate receptor, an excitatory cation channel of which at least three types have been described (kainate, N-methyl-D-aspartate (NMDA) and quisqualate) []. These receptors possess a pentameric structure (made up of varying subunits), surrounding a central pore. All known sequences of subunits from neurotransmitter-gated ion-channels are structurally related. They are composed of a large extracellular glycosylated N-terminal ligand-binding domain, followed by three hydrophobic transmembrane regions which form the ionic channel, followed by an intracellular region of variable length. A fourth hydrophobic region is found at the C-terminal of the sequence [, ]. This domain represents four transmembrane helices of a variety of neurotransmitter-gated ion-channels.; GO: 0006811 ion transport, 0016020 membrane; PDB: 1DXZ_A 3MRA_A 1EQ8_C 1OED_C 2PR9_P 1A11_A 1CEK_A 2BG9_E 2KSR_A 2K59_B ....
