The encoded protein forms an M-channel by associating with the products of the related KCNQ2 or KCNQ5 genes, which both encode integral membrane proteins. M-channel currents are inhibited by M1 muscarinic acetylcholine receptors and are activated by retigabine, a novel anti-convulsant drug. Defects in this gene are a cause of benign familial neonatal convulsions type 2 (BFNC2), also known as epilepsy, benign neonatal type 2 (EBN2). Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2014]. * **UniProt Summary**: Associates with KCNQ2 or KCNQ5 to form a potassium channel with essentially identical properties to the channel underlying the native M-current, a slowly activating and deactivating potassium conductance which plays a critical role in determining the subthreshold electrical excitability of neurons as well as the responsiveness to synaptic inputs. Therefore, it is important in the regulation of neuronal excitability. {ECO:0000269|PubMed:11159685, ECO:0000269|PubMed:14534157, ECO:0000269|PubMed:16319223, ECO:0000269|PubMed:9872318}. |Ion trans 2| |Ion trans| |KCNQ channel| |KCNQC3-Ank-G bd| |membrane hyperpolarization| |node of Ranvier| |axon initial segment| |delayed rectifier potassium channel activity| |voltage-gated potassium channel activity| |voltage-gated potassium channel complex| |potassium ion transmembrane transport| |potassium ion transport| |calmodulin binding| |monovalent inorganic cation transport| |anterograde trans-synaptic signaling| |chemical synaptic transmission| |regulation of membrane potential| |trans-synaptic signaling| |synaptic signaling| |regulation of ion transmembrane transport| |inorganic cation transmembrane transport| |regulation of transmembrane transport| |cation transmembrane transport| |cell surface| |metal ion transport| |inorganic ion transmembrane transport| |regulation of ion transport| |cation transport| |ion transmembrane transport| |cell-cell signaling| |transmembrane transport| |ion transport| |integral component of plasma membrane| |regulation of transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp80|RO-3307 4.7μM R02 exp80]]|1.71| No correlation found to any other genes in chemogenomics.
