Potassium Channels: Complete and Undistorted
The recently determined structure of a mammalian voltage-gated potassium channel has important implications for our understanding of voltage-sensing and gating mechanisms in channels. It is also the first crystal structure of an overexpressed eukaryotic membrane protein.
متن کاملP13: Potassium Channels and Long-Term Potentiation Formation
Long-term potentiation (LTP) is a form of activity-dependent plasticity that occurs during learning. Potassium channels are the most diverse group of all ion channels that related to synaptic plasticity. Small-conductance calcium-activated potassium channels (SKs) are found in hippocampal CA1 neurons and by inhibiting of postsynaptic potentials are involved in synaptic transmission impairment. ...
متن کاملPotassium channels.
The atomic structures of K+ channels have added a new dimension to our understanding of K+ channel function. I will briefly review how structures have influenced our views on ion conduction, gating of the pore, and voltage sensing.
متن کاملATP-sensitive Potassium Channels and L-type Calcium Channels are Involved in Morphine-induced Hyperalgesia after Nociceptive Sensitization in Mice
Introduction: We investigated the role of ATP-sensitive potassium channels and L-type calcium channels in morphine-induced hyperalgesia after nociceptive sensitization. Methods: We used a hotplate apparatus to assess pain behavior in male NMRI mice. Nociceptive sensitization was induced by three days injection of morphine and five days of drug free. On day 9 of the schedule, pain behavior te...
متن کاملMitochondrial potassium and chloride channels.
Channels selective for potassium or chloride ions are present in inner mitochondrial membranes. They probably play an important role in mitochondrial events such as the formation of delta pH and regulation of mitochondrial volume changes. Mitochondrial potassium and chloride channels could also be the targets for pharmacologically active compounds such as potassium channel openers and antidiabe...
