Energy for Life: Coupling Magnesium and ATP regulation Cells require energy for growth and normal functioning. In the cell, energy is stored in the form of ATP molecules, which our bound to magnesium ions. When ATP production increases, the cell requires more magnesium. Recent results from my research team demonstrate that magnesium uptake in cells is facilitated by CNNM-TRPM7 magnesium channels. In the project, I will investigate how the activity of the channel is regulated by the energy needs of the cell. The importance of magnesium for the production and storage of energy will be elucidated.
