TRPM2, a member of the transient receptor potential (TRP) superfamily, is a Ca(2+)-permeable channel activated by oxidative stress or tumor necrosis factoralpha involved in susceptibility to cell death. TRPM2 activation is dependent on the level of intracellular Ca(2+). We explored whether calmodulin (CaM) is the Ca(2+) sensor for TRPM2. HEK 293T cells were(More)
TRPM2 is a Ca(2+)-permeable channel activated by oxidative stress or TNF-alpha, and TRPM2 activation confers susceptibility to cell death. The mechanisms were examined here in human monocytic U937-ecoR cells. This cell line expresses full-length TRPM2 (TRPM2-L) and several isoforms including a short splice variant lacking the Ca(2+)-permeable pore region(More)
