Background: Potassium Channel Kv2.2
The rat potassium channel Kv2.2 subunit is a 95 - 125 kDa, six transmembrane glycoprotein that belongs to the B subfamily of the potassium channel family. It generates a voltage-dependent channel selective for potassium that helps determine the electrical property of smooth muscle cells, various epithelial cell types and neurons. The symbol K stands for potassium, v for the molecule’s ligand (i.e. voltage), 2 for the family type that is determined by similarity to fruit fly genes, and 2 for the gene number within the family. There are two genes within the Kv2 family (Kv2.1 and Kv2.2) that, although co-expressed, preferentially generate homotetramers rather than heterotetramers. Kv2 family members are associated with action potential repolarization. Kv2.2 is particularly noted for setting the resting membrane potential. Low Kv2.2 activity results in hypersensitive neurons.
