Polyamine Block of Inwardly Rectifying Potassium Channels [PDF]

open access: yes, 2011
Polyamine blockade of inwardly rectifying potassium (Kir) channels underlies their steep voltage--dependence observed in native cells. The structural determinants of polyamine blockade and the structure-activity profile of endogenous polyamines requires specialized methodology for characterizing polyamine interactions with Kir channels.

The therapeutic agents that target ATP-sensitive potassium channels

open access: yesActa Pharmaceutica, 2016
ATP-sensitive potassium (KATP) channels are a major drug target for the treatment of type-2 diabetes. KATP channels are ubiquitously expressed and link the metabolic state to electrical excitability.

Cholesterol intake and statin use regulate neuronal G protein-gated inwardly rectifying potassium channels

open access: yesJournal of Lipid Research, 2019
Cholesterol, a critical component of the cellular plasma membrane, is essential for normal neuronal function. Cholesterol content is highest in the brain, where most cholesterol is synthesized de novo; HMG-CoA reductase controls the synthesis rate ...

Subunit gating resulting from individual protonation events in Kir2 channels

open access: yesNature Communications, 2023
Inwardly rectifying potassium (Kir) channels open at the ‘helix bundle crossing’ (HBC), formed by the M2 helices at the cytoplasmic end of the transmembrane pore.

Inwardly Rectifying Potassium Channel Kir2.1 and its “Kir-ious” Regulation by Protein Trafficking and Roles in Development and Disease

open access: yesFrontiers in Cell and Developmental Biology, 2022
Potassium (K+) homeostasis is tightly regulated for optimal cell and organismal health. Failure to control potassium balance results in disease, including cardiac arrythmias and developmental disorders.

Revisit of the Cardiac Inward Rectifier Potassium Current IK1 [PDF]

open access: yes, 2010
Inward rectifier potassium currents are present in different types of cells. In the heart, the inward rectifier potassium current IK1 plays a crucial role in maintaining cardiac resting membrane potential and excitability. It is generally believed that

Direct modulation of G protein-gated inwardly rectifying potassium (GIRK) channels

open access: yesFrontiers in Physiology
Ion channels play a pivotal role in regulating cellular excitability and signal transduction processes. Among the various ion channels, G-protein-coupled inwardly rectifying potassium (GIRK) channels serve as key mediators of neurotransmission and ...

Expression of G-protein inwardly rectifying potassium channels (GIRKs) in lung cancer cell lines

open access: yesBMC Cancer, 2005
Background Previous data from our laboratory has indicated that there is a functional link between the β-adrenergic receptor signaling pathway and the G-protein inwardly rectifying potassium channel (GIRK1) in human breast cancer cell lines. We wanted to

Voltage‐gated and inwardly rectifying potassium channels [PDF]

open access: yesThe Journal of Physiology, 1997
This lecture is dedicated to Max Delbrück and Seymour Benzer. Max Delbrück was our graduate advisor. He introduced us to a variety of biophysical problems, and taught us ways of thinking about these problems by example. Potassium channels was one of the topics included in his journal club in the early seventies; Max also carefully considered the ...

Association Between KCNJ6 (GIRK2) Gene Polymorphism rs2835859 and Post-operative Analgesia, Pain Sensitivity, and Nicotine Dependence

open access: yesJournal of Pharmacological Sciences, 2014
.: G-protein–activated inwardly rectifying potassium (GIRK) channels are expressed in many tissues and activated by several Gi/o protein–coupled receptors, such as opioid and dopamine receptors, and thus are known to be involved in the modulation of ...
