1 Here, we show that while TRPM7"s kinase domain is not essential for activation of its channel, a functional coupling exists such that structural alterations of the kinase domain alter the sensitivity of channel activation to Mg(2+).

2 Investigation of the relationship between Mg(2+) and the cell biological role of TRPM7 revealed that TRPM7-deficient cells become Mg(2+) deficient, that both the viability and proliferation of TRPM7-deficient cells are rescued by supplementation of extracellular Mg(2+), and that the capacity of heterologously expressed TRPM7 mutants to complement TRPM7 deficiency correlates with their sensitivity to Mg(2+).
