Functioni

Calcium-activated non selective (CAN) cation channel that mediates membrane depolarization. While it is activated by increase in intracellular Ca2+, 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 and vomeronasal neurons, endocrine pancreas cells, kidney epithelial cells, cochlea hair cells etc. Participates in T-cell activation by modulating Ca2+ 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 Ca2+ overload. Affects T-helper 1 (Th1) and T-helper 2 (Th2) cell motility and cytokine production through differential regulation of calcium signaling and NFATC1 localization. Enhances cell proliferation through up-regulation of the beta-catenin signaling pathway. Essential for the migration but not the maturation of dendritic cells By similarity.2 Publications

Enzyme regulationi

Gating is voltage-dependent and repressed by decavanadate. Calmodulin-binding confers the Ca2+ sensitivity. ATP is able to restore Ca2+ sensitivity after desensitization. Phosphatidylinositol 4,5-bisphosphate (PIP2)-binding strongly enhances activity, by increasing the channel's Ca2+ sensitivity and shifting its voltage dependence of activation towards negative potentials. Activity is also enhanced by 3,5-bis(trifluoromethyl)pyrazole derivative (BTP2) By similarity.
