Structure-guided unlocking of NaX reveals a non-selective tetrodotoxin-sensitive cation channel
Nature Communications, 2022 NaX is an atypical member of the voltage-gated sodium channel family that may contribute to Na+ homeostasis. Here, the authors describe the structural and functional attributes of the human NaX channel to reveal new insights into its physiology.

Interplay between R513 methylation and S516 phosphorylation of the cardiac voltage-gated sodium channel [PDF]
, 2014 Arginine methylation is a novel post-translational modification within the voltage-gated ion channel superfamily, including the cardiac sodium channel, Naᵥ1.5.

Electrostatic Contributions of Aromatic Residues in the Local Anesthetic Receptor of Voltage-Gated Sodium Channels [PDF]
, 2008 Antiarrhythmics, anticonvulsants, and local anesthetics target voltage-gated sodium channels, decreasing excitability of nerve and muscle cells. Channel inhibition by members of this family of cationic, hydrophobic drugs relies on the presence of highly ...

Nomenclature of Voltage-Gated Sodium Channels [PDF]
Neuron, 2000 Voltage-gated Ca2+ channels mediate calcium influx in response to membrane depolarization and regulate intracellular processes such as contraction, secretion, neurotransmission, and gene expression. They are members of a gene superfamily of transmembrane ion channel proteins that includes voltage-gated K+ and Na+ channels.

Voltage-gated sodium channels potentiate the invasive capacities of human non-small-cell lung cancer cell lines. [PDF]
, 2007 Ionic channel activity is involved in fundamental cellular behaviour and participates in cancerous features such as proliferation, migration and invasion which in turn contribute to the metastatic process.

Deletion of annexin 2 light chain p11 in nociceptors causes deficits in somatosensory coding and pain behavior [PDF]
, 2006 The S100 family protein p11 (S100A10, annexin 2 light chain) is involved in the trafficking of the voltage-gated sodium channel Na(V)1.8, TWIK-related acid-sensitive K+ channel (TASK-1), the ligand-gated ion channels acid-sensing ion channel 1a (ASIC1a ...

SUMOylation of NaV1.2 channels mediates the early response to acute hypoxia in central neurons. [PDF]
, 2016 The mechanism for the earliest response of central neurons to hypoxia-an increase in voltage-gated sodium current (INa)-has been unknown. Here, we show that hypoxia activates the Small Ubiquitin-like Modifier (SUMO) pathway in rat cerebellar granule ...
