Nicotinic Acetylcholine R alpha 7/CHRNA7 Proteins and Enzymes

The nicotinic acetylcholine receptors (nAChRs) are members of a superfamily of ligand-gated ion channels that mediate fast signal transmission at synapses. The nAChRs are thought to be hetero-pentamers composed of homologous subunits. nAChR alpha 7/CHRNA7 forms a homo-oligomeric channel, displays marked permeability to calcium ions and is a major c...
