Gene: Chrna9 (cholinergic receptor nicotinic alpha 9 subunit) Rattus norvegicus
Symbol: Chrna9
Name: cholinergic receptor nicotinic alpha 9 subunit
Description: Exhibits acetylcholine-gated cation-selective channel activity. Involved in negative regulation of ERK1 and ERK2 cascade and sensory perception of sound. Localizes to acetylcholine-gated channel complex; cholinergic synapse; and integral component of postsynaptic specialization membrane. Orthologous to human CHRNA9 (cholinergic receptor nicotinic alpha 9 subunit); PARTICIPATES IN acetylcholine signaling pathway via nicotinic acetylcholine receptor; INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 2,3,7,8-Tetrachlorodibenzofuran; ammonium chloride.
Type: protein-coding
Also known as: acetylcholine receptor alpha 9 subunit (nAChR); cholinergic receptor, nicotinic, alpha 9; cholinergic receptor, nicotinic, alpha 9 (neuronal); cholinergic receptor, nicotinic, alpha polypeptide 9; NACHR alpha 9; NACHR alpha-9; neuronal acetylcholine receptor subunit alpha-9; nicotinic acetylcholine receptor subunit alpha 9; nicotinic acetylcholine receptor subunit alpha-9
