Gene: Kcnq3 (potassium voltage-gated channel subfamily Q member 3) Rattus norvegicus
Symbol: Kcnq3
Name: potassium voltage-gated channel subfamily Q member 3
Description: Exhibits several functions, including calmodulin binding activity; enzyme binding activity; and ion channel binding activity. Involved in cellular response to ammonium ion; nervous system development; and potassium ion transmembrane transport. Localizes to several cellular components, including axon initial segment; membrane raft; and voltage-gated potassium channel complex. Human ortholog(s) of this gene implicated in autistic disorder and benign neonatal seizures. Orthologous to human KCNQ3 (potassium voltage-gated channel subfamily Q member 3); INTERACTS WITH 17alpha-ethynylestradiol; 2,2',4,4'-Tetrabromodiphenyl ether; 6-propyl-2-thiouracil.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: KQT-like 3; potassium channel subunit alpha KvLQT3; potassium channel, voltage-gated KQT-like subfamily Q, member 3; potassium voltage-gated channel subfamily KQT member 3; potassium voltage-gated channel, KQT-like subfamily, member 3; potassium voltage-gated channel, subfamily Q, member 3; voltage-gated potassium channel subunit Kv7.3
