potassium voltage-gated channel subfamily Q member 3
RGD ID:
69222
Description:
Enables several functions, including calmodulin binding activity; enzyme binding activity; and transmembrane transporter binding activity. Involved in cellular response to ammonium ion; nervous system development; and potassium ion transmembrane transport. Located in several cellular components, including axon initial segment; cell surface; and neuronal cell body. Part of 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; 2,3,7,8-tetrachlorodibenzodioxine.
[Tetrachlorodibenzodioxin co-treated with Ethinyl Estradiol] results in increased expression of KCNQ3 mRNA and ESR1 gene mutant form inhibits the reaction [Ethinyl Estradiol results in increased expression of KCNQ3 mRNA]
Astemizole inhibits the reaction [Histamine results in decreased activity of [KCNQ2 protein co-treated with KCNQ3 protein co-treated with HRH1 protein]]
[Benzimidazoles analog results in increased activity of [KCNQ3 protein binds to KCNQ2 protein]] which results in increased import of Thallium and Benzimidazoles analog results in increased activity of [KCNQ3 protein binds to KCNQ2 protein]
Astemizole inhibits the reaction [Histamine results in decreased activity of [KCNQ2 protein co-treated with KCNQ3 protein co-treated with HRH1 protein]] and Histamine results in decreased activity of [KCNQ2 protein co-treated with KCNQ3 protein co-treated with HRH1 protein]
Stoichiometry of expressed KCNQ2/KCNQ3 potassium channels and subunit composition of native ganglionic M channels deduced from block by tetraethylammonium.
