The capsaicin receptor TRPV1 (Transient Receptor Potential, Vanilloid family member 1), the founding member of the heat-sensitive TRP ("thermo-TRP") channel family, plays a pivotal role in pain transduction. There is mounting evidence that TRPV1 regulation is complex and is manifest at many levels, from gene expression through...

The transient receptor potential vanilloid receptor subtype I (TRPV1) channel acts as a polymodal sensory receptor gated by chemical and physical stimuli. Like other TRP channels, TRPV1 contains in its C terminus a short, conserved domain called the TRP box, which is necessary for channel gating. Substitution of two TRP box residues-I696 and...

Coffee, one of the most excessively used beverages worldwide, commences the risk of gastroesophageal reflux (GER), which may lead to gastric ulcers and increase the risk of gastric cancer. Many attempts have been made by the coffee industry to diminish the irritating effect on mucosa by means of altering the extraction methods concerning gerbic...

Transient receptor potential vanilloid receptor subtype 1 (TRPV1) is an ionotropic receptor activated by temperature and chemical stimuli. The C-terminal region that is adjacent to the channel gate, recognized as the TRP domain, is a molecular determinant of receptor assembly. However, the role of this intracellular domain in channel function...

Transient receptor potential vanilloid receptor subtype I (TRPV1) is an ion channel gated by physical and chemical stimuli that belongs to the TRPV protein family. TRPV receptors contain a highly conserved, 6-mer segment near the channel gate, known as the TRP box, whose function remains unknown. Here, we performed an alanine scanning...

Voltage-gated ion channels are modular proteins designed by the structural linkage of a voltage sensor and a pore domain. The functional coupling of these two protein modules is a subject of intense research. A major focus has been directed to decipher the role of the S4-S5 linker and the C-end of the inner pore helix in channel gating....

The thermosensory transient receptor potential vanilloid 1 channel (TRPV1) is a polymodal receptor activated by physical and chemical stimuli. TRPV1 activity is drastically potentiated by proinflammatory agents released upon tissue damage. Given the pivotal role of TRPV1 in human pain, there is pressing need for improved TRPV1 antagonists, the...

Transient receptor potential vanilloid (TRPV1) transduces noxious chemical and physical stimuli in high-threshold nociceptors. The pivotal role of TRPV1 in the physiopathology of pain transduction has thrust the identification and characterization of interacting partners that modulate its cellular function. Here, we report that TRPV1 associates...

The transient receptor potential vanilloid 1 (TRPV1) channel is a thermosensory receptor implicated in diverse physiological and pathological processes. The TRP domain, a highly conserved region in the C terminus adjacent to the internal channel gate, is critical for subunit tetramerization and channel gating. Here, we show that...
