|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Associates with KCNQ3 to form a potassium channel which contributes to M-type current, a slowly activating and deactivating potassium conductance which plays a critical role in determining the subthreshold electrical excitability of neurons. Therefore, it is important in the regulation of neuronal excitability. May contribute, with other potassium channels, to the molecular diversity of a heterogeneous population of M- channels, varying in kinetic and pharmacological properties, which underlie this physiologically important current. Insensitive to tetraethylammonium, but inhibited by barium, linopirdine and XE991. Activated by niflumic acid and the anticonvulsant retigabine. As the native M-channel, the potassium channel composed of KCNQ3 and KCNQ5 is also suppressed by activation of the muscarinic acetylcholine receptor CHRM1.|
|Cellular Location||Cell membrane; Multi-pass membrane protein|
|Tissue Location||Strongly expressed in brain and skeletal muscle. In brain, expressed in cerebral cortex, occipital pole, frontal lobe and temporal lobe. Lower levels in hippocampus and putamen. Low to undetectable levels in medulla, cerebellum and thalamus|

This gene is a member of the KCNQ potassium channel genefamily that is differentially expressed in subregions of the brainand in skeletal muscle. The protein encoded by this gene yieldscurrents that activate slowly with depolarization and can formheteromeric channels with the protein encoded by the KCNQ3 gene.Currents expressed from this protein have voltage dependences andinhibitor sensitivities in common with M-currents. They are alsoinhibited by M1 muscarinic receptor activation. Multiple transcriptvariants encoding different isoforms have been found for this gene.
