Assembly of KATP channels from SUR1 and KIR6.2 [PDF]

open access: yesKidney International, 2001
cretion, and other cellular functions. Unexpectedly, islets Adenosine 5 -triphosphate-sensitive potassium (KATP) from Sur1KO mice are refractory to GLP-1 and GIP, channels are unique combinations of potassium inward gastrointestinal peptides known to potentiate glucoserectifiers (KIR6.x) and sulfonylurea receptors (SURs), induced insulin secretion by ...

Cryo-EM structure of the ATP-sensitive potassium channel illuminates mechanisms of assembly and gating

open access: yeseLife, 2017
KATP channels are metabolic sensors that couple cell energetics to membrane excitability. In pancreatic β-cells, channels formed by SUR1 and Kir6.2 regulate insulin secretion and are the targets of antidiabetic sulfonylureas.

KATP channels are necessary for glucose-dependent increases in amyloid-β and Alzheimer’s disease–related pathology

open access: yesJCI Insight, 2023
Elevated blood glucose levels, or hyperglycemia, can increase brain excitability and amyloid-β (Aβ) release, offering a mechanistic link between type 2 diabetes and Alzheimer’s disease (AD).

The unusual stoichiometry of ADP activation of the KATP channel

open access: yesFrontiers in Physiology, 2014
KATP channels, oligomers of 4 pore-forming Kir6.2 proteins and 4 sulfonylurea receptors (SUR), sense metabolism by monitoring both cytosolic ATP, which closes the channel by interacting with Kir6.2, and ADP, which opens it via SUR.

Zoledronic Acid as a Novel Dual Blocker of KIR6.1/2-SUR2 Subunits of ATP-Sensitive K+ Channels: Role in the Adverse Drug Reactions

open access: yesPharmaceutics, 2021
Zoledronic acid (ZOL) is used as a bone-specific antiresorptive drug with antimyeloma effects. Adverse drug reactions (A.D.R.) are associated with ZOL-therapy, whose mechanics are unknown.

Ankyrin-B Regulates Kir6.2 Membrane Expression and Function in Heart [PDF]

open access: yesJournal of Biological Chemistry, 2010
Ankyrin polypeptides are critical for normal membrane protein expression in diverse cell types, including neurons, myocytes, epithelia, and erythrocytes. Ankyrin dysfunction results in defects in membrane expression of ankyrin-binding partners (including ion channels, transporters, and cell adhesion molecules), resulting in aberrant cellular function ...

KATP channel dependent heart multiome atlas

open access: yesScientific Reports, 2022
Plasmalemmal ATP sensitive potassium (KATP) channels are recognized metabolic sensors, yet their cellular reach is less well understood. Here, transgenic Kir6.2 null hearts devoid of the KATP channel pore underwent multiomics surveillance and systems ...

Cloning and Functional Expression of the Rat Brain KIR6.2 Channel.

open access: yesThe Japanese Journal of Physiology, 1996
We obtained cDNA encoding KIR6.2 channel from the rat brain cDNA library. The reconstituted K+ channel with KIR6.2 and SUR1 genes retained properties similar to those reported in the native ATP-sensitive K+ channel including run-down and recovery of channel activity. When KIR6.2 was co-expressed with CFTR or MDR1, no K+ channel activity was recorded.

Immunohistochemical, pharmacovigilance, and omics analyses reveal the involvement of ATP-sensitive K+ channel subunits in cancers: role in drug–disease interactions

open access: yesFrontiers in Pharmacology, 2023
Background: ATP-sensitive-K+ channels (KATP) are involved in diseases, but their role in cancer is poorly described. Pituitary macroadenoma has been observed in Cantu’ syndrome (C.S.), which is associated with the gain-of-function mutations of the ABCC9 ...

Video3_Simulating PIP2-Induced Gating Transitions in Kir6.2 Channels.MP4

open access: yes, 2021
ATP-sensitive potassium (KATP) channels consist of an inwardly rectifying K+ channel (Kir6.2) pore, to which four ATP-sensitive sulfonylurea receptor (SUR) domains are attached, thereby coupling K+ permeation directly to the metabolic state of the cell ...
