Summary: Enables several functions, including acetylcholine binding activity; acetylcholine-gated cation-selective channel activity; and enzyme binding activity. Involved in several processes, including dopamine biosynthetic process; neuronal action potential; and regulation of ERK1 and ERK2 cascade. Acts upstream of or within calcium ion transport and regulation of membrane potential. Located in several cellular components, including dendrite; plasma membrane raft; and postsynaptic density. Part of acetylcholine-gated channel complex. Is active in cholinergic synapse and glycinergic synapse. Is integral component of postsynaptic specialization membrane; integral component of presynaptic membrane; and integral component of spine apparatus membrane. Human ortholog(s) of this gene implicated in schizophrenia. Orthologous to several human genes including CHRFAM7A (CHRNA7 (exons 5-10) and FAM7A (exons A-E) fusion).

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.
