About This Section Entrez Gene summary for KCNQ2 : The M channel is a slowly activating and deactivating potassium channel that plays a critical role in the regulation of neuronal excitability. The M channel is formed by the association of the protein encoded by this gene and a related protein encoded by the KCNQ3 gene, both integral membrane proteins. M channel currents are inhibited by M1 muscarinic acetylcholine receptors and activated by retigabine, a novel anti-convulsant drug. Defects in this gene are a cause of benign familial neonatal convulsions type 1 (BFNC), also known as epilepsy, benign neonatal type 1 (EBN1). At least five transcript variants encoding five different isoforms have been found for this gene. (provided by RefSeq, Jul 2008) UniProtKB/Swiss-Prot: KCNQ2_HUMAN, O43526 Function : Probably important in the regulation of neuronal excitability. Associates with KCNQ3 to form a potassiumchannel 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. KCNQ2/KCNQ3 current is blocked by linopirdine and XE991, and activated by the anticonvulsant retigabine. Muscarinic agonist oxotremorine-M strongly suppress KCNQ2/KCNQ3 current in cells in which cloned KCNQ2/KCNQ3 channels were coexpressed with M1 muscarinic receptors summary
for KCNQ2 : Voltage-gated potassium channels (KV) belong to the 6-TM family of potassium channel that also comprises theCa2+-activated Slo (actually 7-TM) and the Ca2+-activated SK subfamilies. The pore-forming alpha-subunitscontain a single pore-forming region and combine to form tetramers. Heteromeric channels can be formedwithin subfamilies e.g. KV1.1 with KV1.2 and KCNQ2 with KCNQ3.

About This Section UniProtKB/Swiss-Prot: KCNQ2_HUMAN, O43526 (See
protein sequence )Recommended Name: Potassium voltage-gated channel subfamily KQT member 2 Size : 872 amino acids; 95848 Da
Subunit : Heteromultimer with KCNQ3. May associate with KCNE2
Subcellular location : Membrane; Multi-pass membrane protein
Miscellaneous : Inclusion of isoform 6 in heteromultimers results in attenuation of potassium current. Prominentexpression of isoform 6 in the developing brain may alter firing repertoires of immature neurons excitability to provide cues for proliferation rather than differentiation
Miscellaneous : Mutagenesis experiments were carried out in Xenopus oocytes by coexpression of either KCNQ2(mut) andKCNQ3 at the ratio of 1:1, or of KCNQ2(mut), KCNQ2(wt) and KCNQ3 at the ratio of 1:1:2, to mimic the situation in a heterozygous patient with BFNC1 disease
Secondary accessions : O43796 O75580 O95845 Q4VXP4 Q4VXR6 Q5VYT8 Q96J59 Q99454Alternative splicing : 6 isoforms : O43526-1 O43526-2 O43526-3 O43526-4 O43526-5 O43526-6 (May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay)Explore the universe of human proteins at neXtProt for KCNQ2: NX_O43526 Post-translational modifications:
In Xenopus oocytes KCNQ2/KCNQ3 heteromeric current can be increased by intracellular cyclic AMP, an effect that depends on phosphorylation of Ser-52 in the N-terminus region1

Defects in KCNQ2 are the cause of benign familial neonatal seizures type 1 (BFNS1) [MIM:121200]. A disorder characterized by clusters of seizures occurring in the first days of life. Most patients have spontaneous remission by 12 months of age and show normal psychomotor development. Some rare cases manifest an atypical severe phenotype associated with epileptic encephalopathy and psychomotor retardation. The disorder is distinguished from benign familial infantile seizures by an earlier age at onset. In some patients, neonatal convulsions are followed later in life by myokymia, a benign condition characterized by spontaneous involuntary contractions of skeletal muscles fiber groups that can be observed as vermiform movement of the overlying skin. Electromyography typically shows continuous motor unit activity with spontaneous oligo- and multiplet-discharges of high intraburst frequency (myokymic discharges). Some patients may have isolated myokymia Defects in KCNQ2 are the cause of epileptic encephalopathy early infantile type 7 (EIEE7) [MIM:613720]. EIEE7 is an autosomal dominant seizure disorder characterized by infantile onset of refractory seizures with resultant delayed neurologic development and persistent neurologic abnormalities 20/24 diseases for KCNQ2 (see all 24 ): About MalaCards epileptic encephalopathy, early infantile, 7 convulsions generalized epilepsy with febrile seizures plus seizures, benign neonatal, 1 generalized epilepsy neuroblastoma myokymia with neonatal epilepsy febrile seizures long qt syndrome myokymia idiopathic generalized epilepsy benign neonatal seizures febrile convulsions seizures corpus callosum intellectual disability neuronitis seizure disorder bipolar disorder down syndrome 2 diseases from the University of Copenhagen DISEASES database for KCNQ2 :Brain disease Long QT syndrome 10 Novoseek disease relationships for KCNQ2 gene About this table
