|
A unique functional property within the transient receptor potential (TRP) family of cation channels is the gating of TRP (melastatin) 2 (TRPM2) channels by ADP-ribose (ADPR).

|
ADPR binds to the intracellular C-terminal tail of TRPM2, a domain that shows homology to enzymes with pyrophosphatase activity.

Cytosolic Ca(2+) enhances TRPM2 gating by ADPR; ADPR and Ca(2+) in concert may be an important messenger system mediating Ca(2+) influx.

Other stimuli of TRPM2 include NAD and H(2)O(2) and cyclic ADPR, which may act synergistically with ADPR.

|
The transient potential receptor melastatin-2 (TRPM2) channel has emerged as an important Ca(2+) signalling mechanism in a variety of cells, contributing to cellular functions that include cytokine production, insulin release, cell motility and cell death.

|
Its ability to respond to reactive oxygen species has made TRPM2 a potential therapeutic target for chronic inflammation, neurodegenerative diseases, and oxidative stress-related pathologies.

|
TRPM2 is a non-selective, calcium (Ca(2+))-permeable cation channel of the melastatin-related transient receptor potential (TRPM) ion channel subfamily.
|

|
In addition to its role mediating Ca(2+) influx into the cells, TRPM2 can also function as a lysosomal Ca(2+) release channel, contributing to cell death.

|
The physiological and pathophysiological context of ROS-mediated events makes TRPM2 a promising target for the development of therapeutic tools of inflammatory and degenerative diseases.

|
TRPM2 channel was over-expressed in HEK-293 cells and the whole-cell current was recorded by patch clamp.

|
TRPM2 current was also blocked by Hg(2+), Pb(2+), Fe(2+) and Se(2+).
|

|
We concluded that Cu(2+) is a potent TRPM2 channel blocker.
