Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential. Involved in positive regulation of transmission of nerve impulse. Acts upstream of or within several processes, including behavioral response to nicotine; neuronal action potential; and synaptic transmission involved in micturition. Is active in cholinergic synapse and postsynaptic specialization membrane. Is expressed in several structures, including alimentary system; eye; genitourinary system; nervous system; and thymus. Human ortholog(s) of this gene implicated in cocaine abuse; lung cancer (multiple); nicotine dependence; and oral cavity cancer. Orthologous to human CHRNB4 (cholinergic receptor nicotinic beta 4 subunit). PHENOTYPE: Homozygous mutation of this gene results in hyperplasia of the bladder and altered bladder contractility. Mutant mice also exhibit a resistance to nicotine-induced seizures. [provided by MGI curators] |
