Alternative Name TRPM4 (TRPM4 Antibody Abstract)
Background Function: Calcium-activated non selective (CAN) cation channel that mediates membrane depolarization. While it is activated by increase in intracellular Ca(2+), it is impermeable to it. Mediates transport of monovalent cations (Na(+) > K(+) > Cs(+) > Li(+)), leading to depolarize the membrane. It thereby plays a central role in cadiomyocytes, neurons from entorhinal cortex, dorsal root andvomeronasal neurons, endocrine pancreas cells, kidney epithelial cells, cochlea hair cells etc. Participates in T-cell activation by modulating Ca(2+) oscillations after T lymphocyte activation, which is required for NFAT-dependent IL2 production. Involved in myogenic constriction of cerebral arteries. Controls insulin secretion in pancreatic beta-cells. May also be involved in pacemaking or could cause irregular electrical activity under conditions of Ca(2+) overload.
Enzyme regulation: Gating is voltage-dependent and repressed by decavanadate. Calmodulin-binding confers the Ca(2+) sensitivity. ATP is able to restore Ca(2+) sensitivity after desensitization. Phosphatidylinositol 4,5-biphosphate (PIP2)-binding strongly enhances activity, by increasing the channel's Ca(2+) sensitivity and shifting its voltage dependence of activation towards negative potentials. Activity is also enhanced by 3,5-bis(trifluoromethyl)pyrazole derivative (BTP2).
Subunit: Homomultimer.
Subcellular location: Cell membrane, Multi-pass membrane protein.
Tissue specificity: Widely expressed with a high expression in intestine and prostaste. In brain, it is both expressed in whole cerebral arteries and isolated vascular smooth muscle cells. Also known as: Transient receptor potential cation channel subfamily M member 4, long transient receptor potential channel 4, hTRPM4, melastatin-4, calcium-activated non-selective cation channel 1, TRPM4, TRPM4B, FLJ20041.
