Ultrasound Stimulation Modulates Voltage-Gated Potassium Currents Associated With Action Potential Shape in Hippocampal CA1 Pyramidal Neurons

Frontiers in Pharmacology, 2019
Potassium channels (K+) play an important role in the regulation of cellular signaling. Dysfunction of potassium channels is associated with several severe ion channels diseases, such as long QT syndrome, episodic ataxia and epilepsy.

KCNKØ: opening and closing the 2-P-domain potassium leak channel entails "C-type" gating of the outer pore. [PDF]

, 2001
Essential to nerve and muscle function, little is known about how potassium leak channels operate. KCNKØ opens and closes in a kinase-dependent fashion. Here, the transition is shown to correspond to changes in the outer aspect of the ion conduction pore.

Inactivation in the potassium channel KcsA

Journal of Structural Biology: X, 2019
Inactivation, the slow cessation of transmission after activation, is a general feature of potassium channels. It is essential for their function, and malfunctions in inactivation leads to numerous pathologies. The detailed mechanism for the C-type inactivation, distinct from the N-type inactivation, remains an active area of investigation ...

Inactivation of Kv2.1 Potassium Channels [PDF]

Biophysical Journal, 1998
We report here several unusual features of inactivation of the rat Kv2.1 delayed rectifier potassium channel, expressed in Xenopus oocytes. The voltage dependence of inactivation was U-shaped, with maximum inactivation near 0 mV. During a maintained depolarization, development of inactivation was slow and only weakly voltage dependent (tau = 4 s at 0 ...

Flavonoids as Modulators of Potassium Channels

International Journal of Molecular Sciences, 2023
Potassium channels are widely distributed integral proteins responsible for the effective and selective transport of K+ ions through the biological membranes. According to the existing structural and mechanistic differences, they are divided into several groups.

Immunity to K1 killer toxin: internal TOK1 blockade. [PDF]

, 2001
K1 killer strains of Saccharomyces cerevisiae harbor RNA viruses that mediate secretion of K1, a protein toxin that kills virus-free cells. Recently, external K1 toxin was shown to directly activate TOK1 channels in the plasma membranes of sensitive ...

Unique features of two potassium channels, OsKAT2 and OsKAT3, expressed in rice guard cells. [PDF]

PLoS ONE, 2013
Potassium is the most abundant cation and a myriad of transporters regulate K(+) homeostasis in plant. Potassium plays a role as a major osmolyte to regulate stomatal movements that control water utility of land plants.
