transient receptor potential cation channel subfamily v member 2 is a protein that in humans is encoded by the "trpv2" gene. trpv2 is a nonspecific cation channel that is a part of the trp channel family. this channel allows the cell to communicate with its extracellular environment through the transfer of ions, and responds to noxious temperatures greater than 52 °c. it has a structure similar to that of potassium channels, and has similar functions throughout multiple species; recent research has also shown multiple interactions in the human body.
