Also known as: Acra7; nAchR; alpha7
Summary: Enables acetylcholine-gated monoatomic cation-selective channel activity. Involved in several processes, including plasma membrane bounded cell projection organization; positive regulation of cell communication; and regulation of protein metabolic process. Acts upstream of or within several processes, including behavioral response to ethanol; learning or memory; and negative regulation of cytokine production. Located in apical plasma membrane; axolemma; and external side of plasma membrane. Is active in cholinergic synapse; postsynaptic specialization membrane; and presynaptic membrane. Is expressed in several structures, including adrenal gland; alimentary system; nervous system; retina; and thymus. Used to study schizophrenia. Human ortholog(s) of this gene implicated in chronic obstructive pulmonary disease; esophagus squamous cell carcinoma; respiratory system cancer (multiple); and schizophrenia. Orthologous to human CHRFAM7A (CHRNA7 (exons 5-10) and FAM7A (exons A-E) fusion) and CHRNA7 (cholinergic receptor nicotinic alpha 7 subunit). [provided by Alliance of Genome Resources, Nov 2024]

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.
