MiRP2 forms potassium channels in skeletal muscle with Kv3.4 and is associated with periodic paralysis. [PDF]
Cell, 2001 The subthreshold, voltage-gated potassium channel of skeletal muscle is shown to contain MinK-related peptide 2 (MiRP2) and the pore-forming subunit Kv3.4.

Mitochondrial Potassium Channels as Druggable Targets
Biomolecules, 2020 Mitochondrial potassium channels have been described as important factors in cell pro-life and death phenomena. The activation of mitochondrial potassium channels, such as ATP-regulated or calcium-activated large conductance potassium channels, may have ...

Potassium channel regulation [PDF]
EMBO reports, 2003 The sulphonylurea receptor (SUR) is a member of the ATP-binding cassette (ABC) family of membrane proteins. It functions as the regulatory subunit of the ATP-sensitive potassium (KATP) channel, which comprises SUR and Kir6.x proteins. Here, we review data demonstrating functional differences between the two nucleotide binding domains (NBDs) of SUR1. In

The neuroglial potassium cycle during neurotransmission: role of Kir4.1 channels. [PDF]
PLoS Computational Biology, 2015 Neuronal excitability relies on inward sodium and outward potassium fluxes during action potentials. To prevent neuronal hyperexcitability, potassium ions have to be taken up quickly.

Potassium Ion Channels in Glioma: From Basic Knowledge into Therapeutic Applications
Membranes, 2023 Ion channels, specifically those controlling the flux of potassium across cell membranes, have recently been shown to exhibit an important role in the pathophysiology of glioma, the most common primary central nervous system tumor with a poor prognosis ...

Potassium Channel Mechanics [PDF]
Neuron, 2001 What is the moving part that switches an ion channel's current on and off? In this issue of Neuron del Camino and Yellen (2001) exploit scanning cysteine mutagenesis and sulfhydryl reagents to show that the intracellular end of the S6 helices forms a mechanical gate for the Shaker potassium channel.

Role of Kv1 potassium channels in regulating dopamine release and presynaptic D2 receptor function. [PDF]
PLoS ONE, 2011 Dopamine (DA) release in the CNS is critical for motor control and motivated behaviors. Dysfunction of its regulation is thought to be implicated in drug abuse and in diseases such as schizophrenia and Parkinson's.
