[[http://www.uniprot.org/uniprot/ACHA9_HUMAN ACHA9_HUMAN]] Ionotropic receptor with a probable role in the modulation of auditory stimuli. Agonist binding may induce an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane. The channel is permeable to a range of divalent cations including calcium, the influx of which may activate a potassium current which hyperpolarizes the cell membrane. In the ear, this may lead to a reduction in basilar membrane motion, altering the activity of auditory nerve fibers and reducing the range of dynamic hearing. This may protect against acoustic trauma. May also regulate keratinocyte adhesion.<ref>PMID:11752216</ref> <ref>PMID:11021840</ref> [[http://www.uniprot.org/uniprot/NXL1V_BUNMU NXL1V_BUNMU]] Produces peripheral paralysis by blocking neuromuscular transmission at the postsynaptic site. Binds to muscular and neuronal (alpha-7, alpha-8, and alpha-9) nicotinic acetylcholine receptors.
