General annotation (Comments)

Function

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 By similarity. Essential for the migration but not the maturation of dendritic cells. Ref.5 Ref.6

Enzyme regulation

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. Inhibited by flufenamic acid and glibenclamide. Ref.5

Subunit structure

Homomultimer By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein. Endoplasmic reticulum By similarity. Golgi apparatus By similarity Ref.1.

Tissue specificity

Sino-atrial nodes (at protein level). Widely expressed. Ref.1 Ref.2 Ref.5

Post-translational modification

Phosphorylation by PKC leads to increase the sensitivity to Ca2+ By similarity.

Sumoylated. Desumoylated by SENP1 By similarity.

Disruption phenotype

Mice have fewer dendritic cells in lymphoid organs and impaired migration of dendritic cells is seen. Ref.6

Sequence similarities

Belongs to the transient receptor (TC 1.A.4) family. LTrpC subfamily. TRPM4 sub-subfamily. [View classification]
