Ligand-gated ion channel Example : nicotinicWikipedia, From
Each subunit of the pentameric channels consist of the extracellular ligand-binding domain and a transmembrane domain. Each transmembrane domain in the pentamer includes four transmembrane helixes.[2] Example: nicotinic acetylcholine receptorThe prototypic ligand-gated ion channel is the nicotinic ...
For example, the 5HT3 receptor activated by serotonin is a ligand-gated ion channel (Julius, 1991). ATP is released from nerve terminals in several pathways and activates the P2X family of channels (Burnstock, 2007; Browne et al., 2010). The transient receptor potential (TRP) channels ...
GABAAand GABAA-ρ receptorsare ligand-gated ion channels, which, along with the G-protein coupledGABABreceptors, mediate the effects of GABA. GABA is the major inhibitory neurotransmitter in the central nervous system and is present in interneurons and projection neurons throughout the brain, and ...

The present invention relates in part to isolated nucleic acid molecules (polynucleotides) which encode Dermacentor variabilis ligand gated ion channel proteins. The present
(seechelating agents). Ethylenediamine-tetraacetate, a commonly used chelating compound, has six pairs of electrons to bind to metal ions. Electron-donating functional groups containing nitrogen, oxygen, sulfur, phosphorous, or carbon may act as ligands in complex biological systems. For example, in...
Overview: Ligand-gated ion channels (LGICs) are integral mem- brane proteins that contain a pore which allows the regulated flow of selected ions across the plasma membrane. Ion flux is pas- sive and driven by the electrochemical gradient for the perme- ant ions. These c...
