| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Essential ion channel and serine/threonine-protein kinase. Divalent cation channel permeable to calcium and magnesium. Has a central role in magnesium ion homeostasis and in the regulation of anoxic neuronal cell death. The kinase activity is essential for the channel function. May be involved in a fundamental process that adjusts plasma membrane divalent cation fluxes according to the metabolic state of the cell. Phosphorylates annexin A1 (ANXA1). Ref.6 Ref.7 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Binds 1 zinc ion per subunit By similarity. |
| Subunit structure | Homodimer. Interacts with PLCB1 By similarity. Forms heterodimers with TRPM6. Ref.8 |
| Subcellular location | Membrane; Multi-pass membrane protein Probable. |
| Post-translational modification | Autophosphorylated By similarity. |
| Involvement in disease | Amyotrophic lateral sclerosis-parkinsonism/dementia complex 1 (ALS-PDC1) [MIM:105500]: A neurodegenerative disorder characterized by chronic, progressive and uniformly fatal amyotrophic lateral sclerosis and parkinsonism-dementia. Both diseases are known to occur in the same kindred, the same sibship and even the same individual. |
| Sequence similarities | In the C-terminal section; belongs to the protein kinase superfamily. Alpha-type protein kinase family. ALPK subfamily. In the N-terminal section; belongs to the transient receptor (TC 1.A.4) family. LTrpC subfamily. TRPM7 sub-subfamily. [View classification] Contains 1 alpha-type protein kinase domain. |
| Sequence caution | The sequence BAC11462.1 differs from that shown. Reason: Erroneous initiation. The sequence BAD18773.1 differs from that shown. Reason: Erroneous initiation. |
