VOLTAGE-GATED ION CHANNELS Voltage-Gated Sodium Channels
Antiepileptic drugs (AEDs) protect against seizures through interactions with a variety of cellular targets. By affecting the functional activity of these targets, AEDs suppress abnormal hypersynchronous activity in brain circuits, leading to protection against seizures. The actions on these targets can be categorized into four broad groups: (i) modulation of voltage-gated ion channels, includi...
متن کاملVoltage sensor interaction site for selective small molecule inhibitors of voltage-gated sodium channels.
Voltage-gated sodium (Nav) channels play a fundamental role in the generation and propagation of electrical impulses in excitable cells. Here we describe two unique structurally related nanomolar potent small molecule Nav channel inhibitors that exhibit up to 1,000-fold selectivity for human Nav1.3/Nav1.1 (ICA-121431, IC50, 19 nM) or Nav1.7 (PF-04856264, IC50, 28 nM) vs. other TTX-sensitive or ...
متن کاملReconstructing Voltage Sensor–Pore Interaction from a Fluorescence Scan of a Voltage-Gated K+ Channel
X-ray crystallography has made considerable recent progress in providing static structures of ion channels. Here we describe a complementary method-systematic fluorescence scanning-that reveals the structural dynamics of a channel. Local protein motion was measured from changes in the fluorescent intensity of a fluorophore attached at one of 37 positions in the pore domain and in the S4 voltage...

differentiated newt cells, but not in their mammalian counterparts. There has been some progress along these lines but not at the level of pinpointing the genetic differences. It is important to remember that there are examples, such as the axolotl lens, where a particular tissue does not regenerate even though the animal is capable of regenerating other structures. Such a context may be more f...
متن کاملVoltage-gated Proton “Channels”
A battle is raging over the molecular identity of the voltage-gated, H -selective conductance that has been recorded in activated and/or depolarized phagocytes. Having stepped out of this arena, we feel uncommitted to any particular viewpoint and hope to be able to provide below an unbiased opinion of what we feel has been established unambiguously, and what requires additional confirmation bef...
