TRPM5 (Transient Receptor Potential Melastatin 5) is a member of the TRP (transient receptor potential) ion channel family. It is primarily expressed in certain sensory cells, particularly those involved in taste and in the inner ear. TRPM5 is a calcium-permeable cation channel that is activated by variations in intracellular calcium levels and is known to play a significant role in signal transduction processes.
