Scientific Background
KV2.2 is a member of the voltage-gated K+ channel superfamily. Together with the closely related KV2.1 protein they form the KV2 subfamily also known as Shab1-3.
As with all KV channels, KV2.2 possesses the signature structure of the voltage-dependent K+ channels: six membrane-spanning domains with intracellular N and C termini. The functional KV channel is a tetramer that can either be a homotetramer or a heteromer of KV2.2 and KV2.1 subunits1-3.
The pharmacology of the KV2.2 channel is somewhat limited. The channel is blocked by the classical K+ channel blockers tetraethylammonium (TEA) and 4-aminopyridine (4-AP). More recently, the small peptide toxin Stromatoxin-1 has been found to be a potent and more specific inhibitor of the KV2 subfamily4.
