GeneCards Summary for TRPM8 Gene
TRPM8 (Transient Receptor Potential Cation Channel Subfamily M Member 8) is a Protein Coding gene. Diseases associated with TRPM8 include Migraine Without Aura and Dentin Sensitivity. Among its related pathways are Ion channel transport and TRP channels. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and calcium channel activity. An important paralog of this gene is TRPM2.
UniProtKB/Swiss-Prot Summary for TRPM8 Gene
Receptor-activated non-selective cation channel involved in detection of sensations such as coolness, by being activated by cold temperature below 25 degrees Celsius. Activated by icilin, eucalyptol, menthol, cold and modulation of intracellular pH. Involved in menthol sensation. Permeable for monovalent cations sodium, potassium, and cesium and divalent cation calcium. Temperature sensing is tightly linked to voltage-dependent gating. Activated upon depolarization, changes in temperature resulting in graded shifts of its voltage-dependent activation curves. The chemical agonist menthol functions as a gating modifier, shifting activation curves towards physiological membrane potentials. Temperature sensitivity arises from a tenfold difference in the activation energies associated with voltage-dependent opening and closing. In prostate cancer cells, shows strong inward rectification and high calcium selectivity in contrast to its behavior in normal cells which is characterized by outward rectification and poor cationic selectivity. Plays a role in prostate cancer cell migration (PubMed:25559186). Isoform 2 and isoform 3 negatively regulate menthol- and cold-induced channel activity by stabilizing the closed state of the channel.
The melastatin-related receptor family (TRPM) is the largest subfamily of the transient receptor potential (TRP) superfamily of ion channels. It contains 8 known members, subdivided into 4 groups, which perform a range of functions including detection of taste and osmolarity.
