Ion channel regulation by protein S-acylation

The Journal of General Physiology, 2014
Protein S-acylation, the reversible covalent fatty-acid modification of cysteine residues, has emerged as a dynamic posttranslational modification (PTM) that controls the diversity, life cycle, and physiological function of numerous ligand- and voltage ...

Molecular determinants of signal transduction in tropomyosin receptor kinases

FEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Gating modulation and potentiation of amiodarone blockage of the Kv10.1 potassium channel bu KB130015, an amiodarone derived molecule

Channels
Kv10.1 is a voltage-gated K+ channel whose structure–function relationships remain incompletely understood, and whose ectopic expression is linked to tumorigenesis.

TRPV4 Mediates Acute Bladder Responses to Bacterial Lipopolysaccharides

Frontiers in Immunology, 2020
Urinary tract infections (UTI) affect a large proportion of the population, causing among other symptoms, more frequent and urgent micturition. Previous studies reported that the gram-negative bacterial wall component lipopolysaccharides (LPS) trigger ...

More Than a Pore: Ion Channel Signaling Complexes

Journal of Neuroscience, 2014
Voltage- and ligand-gated ion channels form the molecular basis of cellular excitability. With >400 members and accounting for ∼1.5% of the human genome, ion channels are some of the most well studied of all proteins in heterologous expression systems ...

Calcium‐sensing receptor induces the apoptosis of chondrocytes in cooperation with phosphate transporter

FEBS Open Bio, EarlyView.
Excess Ca2+ ions activate the Calcium‐Sensing Receptor (CaSR), which subsequently drives the uptake of excess inorganic phosphate (Pi) via the Pi transporter (Pit−1) in chondrocytes. This mechanism causes a toxic increase in intracellular Pi concentration, ultimately leading to chondrocyte apoptosis and pathological mineralization. Excess extracellular

The photoswitchable cannabinoid azo‐HU308 enables optical control of Ca2+ dynamics in INS‐1 β‐cells via off‐target effects on TRPC channels

FEBS Open Bio, EarlyView.
Light activation of the photoswitchable cannabinoid ligand azo‐HU308 triggers Ca2+ influx in pancreatic β‐cells through TRPC channels, independent of CB2 cannabinoid receptors. This reveals a non‐GPCR pathway for cannabinoid modulation of β‐cell Ca2+ dynamics and establishes azo‐HU308 as an optical tool to study cannabinoid signaling through TRP ...

Electrophysiological classification of CACNA1G gene variants associated with neurodevelopmental and neurological disorders

Frontiers in Pharmacology
This study highlights the complementarity of automated patch-clamp (APC) and manual patch-clamp (MPC) approaches to describe the electrophysiological properties of eighteen Cav3.1 calcium channel variants associated with various neurological conditions ...

Voltage-Gated K+/Na+ Channels and Scorpion Venom Toxins in Cancer

Frontiers in Pharmacology, 2020
Ion channels have recently been recognized as novel therapeutic targets in cancer research since they are overexpressed in different histological tissues, and their activity is linked to proliferation, tumor progression, angiogenesis, metastasis, and ...
