靶點詳情

  • 功能：
    Potassium channel that plays an important role in a number of tissues, including heart, inner ear, stomach and colon. Associates with KCNE beta subunits that modulates current kinetics. Induces a voltage-dependent by rapidly activating and slowly deactivating potassium-selective outward current. Promotes also a delayed voltage activated potassium current showing outward rectification characteristic. During beta-adrenergic receptor stimulation participates in cardiac repolarization by associating with KCNE1 to form the I(Ks) cardiac potassium current that increases the amplitude and slows down the activation kinetics of outward potassium current I(Ks). Muscarinic agonist oxotremorine-M strongly suppresses KCNQ1/KCNE1 current. When associated with KCNE3, forms the potassium channel that is important for cyclic AMP-stimulated intestinal secretion of chloride ions. This interaction with KCNE3 is reduced by 17beta-estradiol, resulting in the reduction of currents. During conditions of increased substrate load, maintains the driving force for proximal tubular and intestinal sodium ions absorption, gastric acid secretion, and cAMP-induced jejunal chloride ions secretion. Allows the provision of potassium ions to the luminal membrane of the secretory canaliculus in the resting state as well as during stimulated acid secretion. When associated with KCNE2, forms an heterooligomer complex leading to currents with an apparently instantaneous activation, a rapid deactivation process and a linear current-voltage relationship and decreases the amplitude of the outward current. When associated with KCNE4, inhibits voltage-gated potassium channel activity. When associated with KCNE5, this complex only conducts current upon strong and continued depolarization. Also forms a heterotetramer with KCNQ5; has a voltage-gated potassium channel activity. Binds with phosphatidylinositol 4,5-bisphosphate.

    2. Collectively, the authors propose that Prmt1-dependent facilitation of KCNQ-phosphatidylinositol-4,5-bisphosphate interaction underlies the positive regulation of KCNQ activity by arginine methylation, which may serve as a key target for prevention of neuronal hyperexcitability and seizures. PMID: 27466704
    3. we investigated the effects of KCNQ1 A340E, a loss-of-function mutant. J343 mice bearing KCNQ1 A340E demonstrated a much higher 24-h intake of electrolytes (potassium, sodium, and chloride). KCNQ1, therefore, is suggested to play a central role in electrolyte metabolism. KCNQ1 A340E, with the loss-of-function phenotype, may dysregulate electrolyte homeostasis PMID: 27525866

    18. KCNQ1 loss-of-function mutation impairs gastric acid secretion in mice. PMID: 19306073
    19. Data suggest that because the abundance and subcellular localization of KCNQ1 was unchanged in kcne3(-/-) mice, the modification of biophysical properties of KCNQ1 by KCNE3 is essential for its role in intestinal and tracheal transport. PMID: 20051516
    20. Loss of Igf2 imprinting in monoclonal mouse hepatic tumor cells is not associated with abnormal methylation patterns for the H19 and Igf2 differentially methylated regions. PMID: 12475990
