In Drosophila, trypsin treatments can alter the behavior of the Shaker type of these, and mice with a Weaver mutation in the G-protein-activated inwardly rectifying type suffer degeneration of midbrain dopaminergic neurons.
Mutations in the KCNQ2 type of these objects can cause neonatal epilepsy, and limbic encephalitis may result from antibodies attacking them. In Drosophila, trypsin treatments can alter the behavior of the Shaker type of these, and mice with a Weaver mutation in the G-protein-activated inwardly rectifying type suffer degeneration of midbrain dopaminergic neurons. Typically, they are composed of 4 subunits, each featuring a protein with six transmembrane domains. An arrangement of five carbonyl oxygens in these structures highly selectively removes the hydration shell from a certain type of ion. Compounds that block these, such as bretylium, are used to treat arrhythmias, and the opening of the voltage-gated type of these causes the falling phase of the action potential. FTP, name this type of ion channel that regulates positive ions with atomic number nineteen.
