  • Function

    Nonselective, voltage-independent cation channel mediating sodium and calcium ion influx in response to oxidative stress. Extracellular calcium passes through the channel and acts from the intracellular side as a positive regulator in channel activation. Activated by ADP-ribose, nicotinamide adenine dinucleotide (NAD(+)), reactive nitrogen species and arachidonic acid. Inactivated by intracellular ATP. Confers susceptibility to cell death following oxidative stress. Isoform 2 does not seem to be regulated by ADPR. Has ADP-ribose pyrophosphatase activity.
  • Tissue specificity

    Highly expressed in brain and peripheral blood cells, such as neutrophils. Also detected in bone marrow, spleen, heart, liver and lung. Isoform 2 is found in neutrophil granulocytes.
  • Sequence similarities

    Belongs to the transient receptor (TC 1.A.4) family. LTrpC subfamily. TRPM2 sub-subfamily.
    Contains 1 nudix hydrolase domain.

  • Paraformaldehyde-fixed, 0.15% Triton X-100 permeabilized A431 (human epidermoid carcinoma cell line) cells stained for TRPM2 (green) using ab240540 at 10 μg/ml for 1 hour followed by an Alexa Fluor® 488-conjugated secondary antibody in ICC/IF. The nuclear counter stain is DAPI (blue).

    The negative control is unimmunized goat IgG at 10 μg/ml followed by an Alexa Fluor® 488-congugated secondary antibody.

  • Flow cytometric analysis of paraformaldehyde-fixed, 0.5% Triton X-100 permeabilized Jurkat (human T cell leukemia cell line from peripheral blood) cells labeling TRPM2 with ab240540 at 10 μg/ml (blue) compared to an unimmunized goat IgG negative control (black). The secondary antibody is AlexaFluor® 488-conjugated antibody at 1 μg/ml.
