Gene Summary
- Human (1138): Nicotinic acetylcholine receptors (nAChRs), such as CHRNA5, 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. See MIM 118508 for additional background information on AChRs.[supplied by OMIM]
- Rat (25102): neuronal receptor and ion channel activated by acetylcholine; mediates release of catecholamines into bloodstream [RGD]
