DESCRIPTION

Also known as KCNQ4_HUMAN, KCNQ4. Probably important in the regulation of neuronal excitability. May underlie a potassium current involved in regulating the excitability of sensory cells of the cochlea. KCNQ4 channels are blocked by linopirdin, XE991 and bepridil, whereas clofilium is without significant effect. Muscarinic agonist oxotremorine-M strongly suppress KCNQ4 current in CHO cells in which cloned KCNQ4 channels were coexpressed with M1 muscarinic receptors. Homotetramer. May form heteromultimers with KCNQ3. Interacts with HSP90AB1; promotes cell surface expression of KCNQ4 (PubMed:23431407).
