Enables inorganic cation transmembrane transporter activity. Involved in magnesium ion transport. Located in plasma membrane. Used to study primary hypomagnesemia.
SGD Description
Plasma membrane Mg(2+) transporter; expression and turnover are regulated by Mg(2+) concentration; overexpression confers increased tolerance to Al(3+) and Ga(3+) ions; magnesium transport defect of the null mutant is functionally complemented by either of the human genes MAGT1 and TUSC3 that are not orthologous to ALR1
