High level production, characterization and structural analysis of neuronal calcium-activated potassium channels

open access: yes, 2004
Kaliumkanäle vermitteln als reguliertes Porenprotein den selektiven Transport von Kaliumionen durch die Zellmembran. Sie sind für physiologische Prozesse wie Neurosekretion und Tonus der glatten Muskulatur von Bedeutung.

NFATc3 regulates BK channel function in murine urinary bladder smooth muscle

open access: yes, 2008
The nuclear factor of activated T-cells (NFAT) is a Ca2+- dependent transcription factor that has been reported to regulate the expression of smooth muscle contractile proteins and ion channels.

An inhibitor of the Kv2.1 potassium channel isolated from the venom of a Chilean tarantula

open access: yes, 1995
The Kv2.1 voltage-activated K+ channel, a Shab-related K+ channel isolated from rat brain, is insensitive to previously identified peptide inhibitors. We have isolated two peptides from the venom of a Chilean tarantula, G. spatulata, that inhibit the Kv2.

Inhibition of Kv2.1 voltage-dependent K+ channels in pancreatic beta-cells enhances glucose-dependent insulin secretion

open access: yes
Voltage-dependent (Kv) outward K(+) currents repolarize beta-cell action potentials during a glucose stimulus to limit Ca(2+) entry and insulin secretion.

Mechanisms of Homeostatic Control of Neuronal Intrinsic Excitability [PDF]

open access: yes, 2019
A neuron’s identity and function are dictated by its electrophysiological signature. The firing pattern of a neuron emerges from the particular combination of ion channels in its membrane. A neuron can “tune” the combination of ionic conductances that it

Signal transformation at the input and output of the Drosophila visual system

open access: yes, 2017
A key function of the nervous system is to sample data from the external world, generate internal signals, and transform them into meaningful information that can be used to trigger behaviour.

Kinetic study of interactions between voltage-gated K+-channels and toxins from spider venom

open access: yes, 2007
電壓感應開啟式鉀離子通道(Voltage-gated potassium channel, Kv channel)普遍存在於各類組織,主要負責在細胞膜興奮時開啟,造成再極化。通常由四個次單元體組成,每個次單元體上含有通道形成區域(pore-forming domain)及四個電壓感受過膜片段(voltage-sensing transmembrane segments),稱之為S1-S4。其中S4是最主要的電壓感受體(voltage sensor)。又目前已知S3的C端(S3C)可與通道開啟調整毒素 ...

Vitamin D and endothelial function in chronic kidney disease [PDF]

open access: yes, 2014
PhDVitamin D deficiency in patients with chronic kidney disease, measured by reduced serum concentrations of 25 hydroxy vitamin D, is highly prevalent and associated with both endothelial dysfunction and an increased risk of cardiovascular disease ...
