Predicted to enable ATP binding activity and magnesium ion transmembrane transporter activity. Predicted to be involved in magnesium ion homeostasis. Predicted to act upstream of or within magnesium ion transport. Predicted to be located in basolateral plasma membrane. Predicted to be active in intracellular membrane-bounded organelle and plasma membrane. Human ortholog(s) of this gene implicated in renal hypomagnesemia 6. Orthologous to human CNNM2 (cyclin and CBS domain divalent metal cation transport mediator 2). [provided by Alliance of Genome Resources, Apr 2022]
