Research Abstract
The Hoshi laboratory studies physiological role and regulation of the M-channel, a sub-threshold ion channel that regulates neuronal excitability. We have demonstrated that the AKAP150 macromolecular complex integrates multiple signals to regulate this channel. Genetic removal of AKAP150 resulted in tolerance to seizure induction. One of our goals is to control pathological neuronal activity through the M-channel modulators. The laboratory is now focused on understanding the physiological and pathological role of M-current suppression in learning and memory as well as in seizures. The laboratory utilizes molecular biology, electrophysiology, live cell FRET imaging and behavioral neuroscience.
