CC -!- FUNCTION: Alpha subunit of nicotinic acetylcholine receptor (nAChR)
CC (PubMed:9221782, PubMed:15990870, PubMed:20027209). Probably acts in
CC cholinergic motoneurons to regulate presynaptic neurotransmitter
CC release, thereby ensuring normal level of excitation of cholinergic
CC motoneurons during locomotion (PubMed:20027209). Involved in nAChR
CC sensitivity to nicotine (PubMed:9221782, PubMed:15990870).
CC {ECO:0000269|PubMed:15990870, ECO:0000269|PubMed:20027209,
CC ECO:0000269|PubMed:9221782}.
CC -!- SUBUNIT: Component of nicotinic acetylcholine receptor
CC (PubMed:15990870, PubMed:20027209). In muscles, composed of 2 non-alpha
CC subunits lev-1 and unc-29, and 3 alpha subunits unc-38, unc-63 and lev-
CC 8 (PubMed:15990870). In cholinergic motoneurons, composed of 2 non-
CC alpha subunits acr-2 and acr-3, and 3 alpha subunits unc-38, unc-63 and
CC acr-12 (PubMed:20027209). {ECO:0000269|PubMed:15990870,
CC ECO:0000269|PubMed:20027209}.
CC -!- SUBCELLULAR LOCATION: Postsynaptic cell membrane
CC {ECO:0000269|PubMed:15990870}; Multi-pass membrane protein
CC {ECO:0000255}. Cell membrane {ECO:0000269|PubMed:15990870}; Multi-pass
CC membrane protein {ECO:0000255}. Note=Co-localizes with unc-29 and lev-1
CC and partially with acr-12 and acr-8 at nerve cord synapses.
CC {ECO:0000269|PubMed:15990870}.
CC -!- DISRUPTION PHENOTYPE: RNAi-mediated knockdown causes a resistance to
CC nicotine-mediated paralysis. {ECO:0000269|PubMed:15990870}.
CC -!- SIMILARITY: Belongs to the ligand-gated ion channel (TC 1.A.9) family.
CC Acetylcholine receptor (TC 1.A.9.1) subfamily. {ECO:0000305}.
