Transient receptor potential cation channel subfamily M member 5 (TRPM5), also known as long transient receptor potential channel 5 is a protein that in humans is encoded by the TRPM5 gene.[1][2]

Function[edit]

TRPM5 is a key component of taste transduction in the gustatory system of bitter, sweet and umami tastes being activated by high levels of intracellular calcium. It has also been targeted as a possible contributor to fat taste signaling.[3][4] The calcium dependent opening of TRPM5 produces a depolarizing generator potential which leads to an action potential.[5]
