Transient receptor potential (TRP) channels modulate calcium levels in, eukaryotic cells in response to external signals. A novel transient, receptor potential channel has the ability to phosphorylate itself and, other proteins on serine and threonine residues. The catalytic domain of, this channel kinase has no detectable sequence similarity to classical, eukaryotic protein kinases and is essential for channel function. The, structure of the kinase domain, reported here, reveals unexpected, similarity to eukaryotic protein kinases in the catalytic core as well as, to metabolic enzymes with ATP-grasp domains. The inclusion of the channel, kinase catalytic domain within the eukaryotic protein kinase superfamily, indicates a significantly wider distribution for this group of signaling, proteins than suggested previously by sequence comparisons alone.

== Function ==
 +
[https://www.uniprot.org/uniprot/TRPM7_MOUSE TRPM7_MOUSE] 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>PMID:11385574</ref>
