Acetylcholine, released by cholinergic neurons, activates two groups of acetylcholine receptors (AChRs); muscarinic AChRs (mAChRs) which belong to the superfamily of G-protein coupled receptors (GPCRs) and nicotinic AChRs (nAChRs) which belong to the ligand-gated ion channel superfamily. nAChRs also respond to nicotine, hence their name1. To date, 17 different but related subunits of nAChRs have been identified and cloned. They consist of a subunits (α1-10), which are responsible for the binding of ligands. In fact, this subunit includes a Cys-loop in the first extracellular domain that is required for agonist binding2. The other subunits responsible for making up the active receptor are the β (β1-4), γ, δ and ε subunits3. Structurally, all subunits have the following: a conserved large extracellular N-terminal domain, 3 conserved transmembrane domains, a variable cytoplasmic loop and a fourth transmembrane domain with a short extracellular C-terminal domain. An active nAChR is generally a heteropentamer of these various subunits organized around a central pore1. While most β subunits are neuronal, the β1 subunit forms functional receptors along with other subunits in the muscle3. In neurons the α2-α6 and β2-β4 subunits form heteropentameric receptors, usually with a (αx)2(βy)3 stoichiometry3. Abgent is pleased to offer a highly specific antibody directed against an extracellular epitope of rat Nicotinic Acetylcholine Receptor β4 (nAChRβ4). Anti-Nicotinic Acetylcholine Receptor β4 (extracellular) antibody (#AG1197) can be used in western blot analysis and immunocytochemistry applications, and has been designed to recognize nAChRβ4 from mouse, rat and human samples.
