Summary: Enables acetylcholine binding activity; heterocyclic compound binding activity; and postsynaptic neurotransmitter receptor activity. Involved in several processes, including acetylcholine receptor signaling pathway; regulation of synaptic vesicle exocytosis; and response to nicotine. Located in several cellular components, including neuronal cell body; plasma membrane raft; and postsynaptic density. Part of acetylcholine-gated channel complex. Is active in cholinergic synapse and dopaminergic synapse. Is integral component of postsynaptic specialization membrane. Used to study visual epilepsy.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
