TRPM7 protein structure. The protein comprises 4 melastatin homologous regions in the N-terminal domain and 6 transmembrane segments with a pore region located between segments 5 and 6. The C-terminal domain consists of the transient receptor potential region, followed by the connecting loop of the coiled-coil domain and the serine/threonine protein kinase domain, which is able to phosphorylate substrates and regulate the activity of downstream target proteins.30,31 Abbreviations: MHR, melastatin homologous regions; TRP, transient receptor potential.
