Ras-association domain of sorting Nexin 27 is critical for regulating expression of GIRK potassium channels. [PDF]

open access: yesPLoS ONE, 2013
G protein-gated inwardly rectifying potassium (GIRK) channels play an important role in regulating neuronal excitability. Sorting nexin 27b (SNX27b), which reduces surface expression of GIRK channels through a PDZ domain interaction, contains a putative ...

Perisynaptic astrocytes as a potential target for novel antidepressant drugs

open access: yesJournal of Pharmacological Sciences, 2021
Emerging evidence suggests that dysfunctions in glutamatergic signaling are associated with the pathophysiology of depression. Several molecules that act on glutamate binding sites, so-called glutamatergic modulators, are rapid-acting antidepressants ...

Pharmacological Characterization of 5-HT1A Autoreceptor-Coupled GIRK Channels in Rat Dorsal Raphe 5-HT Neurons.

open access: yesPLoS ONE, 2015
G protein-activated inwardly rectifying potassium (GIRK) channels in 5-HT neurons are assumed to be principal effectors of 5-hydroxytryptamine 1A (5-HT1A) autoreceptors, but their pharmacology, subunit composition and the role in regulation of 5-HT ...

A G protein-gated K channel is activated via beta 2-adrenergic receptors and G beta gamma subunits in Xenopus oocytes [PDF]

open access: yes, 1995
In many tissues, inwardly rectifying K channels are coupled to seven- helix receptors via the Gi/Go family of heterotrimeric G proteins. This activation proceeds at least partially via G beta gamma subunits.

Effects of cromakalim (BRL 34915) on potassium conductances in CA3 neurons of the guinea-pig hippocampus in vitro [PDF]

open access: yes, 1989
The action of the potassium channel activator, cromakalim (BRL 34915), on membrane potential, input resistance and current-voltage-relationship of CA3 neurons in a slice preparation of the guinea-pig hippocampus was investigated by means of intracellular

Involvement of spinal G-protein inwardly rectifying potassium (GIRK) channels in the enhanced antinociceptive effects of the activation of both μ-opioid and cannabinoid CB1 receptors

open access: yesJournal of Pharmacological Sciences, 2022
Neuropathic pain is refractory to opioid analgesics. Since there are functional linkages between μ-opioid receptors (MOR) and cannabinoid receptors (CBR), the present study was designed to investigate the interactions between MOR and CB1R based on ...

CO2-dependent opening of an inwardly rectifying K+ channel [PDF]

open access: yes, 2011
CO2 chemosensing is a vital function for the maintenance of life that helps to control acid–base balance. Most studies have reported that CO2 is measured via its proxy, pH. Here we report an inwardly rectifying channel, in outside-out excised patches

Inwardly rectifying potassium channels mediate polymyxin-induced nephrotoxicity

open access: yesCellular and Molecular Life Sciences, 2022
AbstractPolymyxin antibiotics are often used as a last-line defense to treat life-threatening Gram-negative pathogens. However, polymyxin-induced kidney toxicity is a dose-limiting factor of paramount importance and can lead to suboptimal treatment. To elucidate the mechanism and develop effective strategies to overcome polymyxin toxicity, we employed ...

Intrinsic Gating Properties of a Cloned G Protein-activated Inward Rectifier K^+ Channel [PDF]

open access: yes, 1995
The voltage-, time-, and K^+-dependent properties of a G protein-activated inwardly rectifying K^+ channel (GIRK1/KGA/Kir3.1) cloned from rat atrium were studied in Xenopus oocytes under two-electrode voltage clamp. During maintained G protein activation
