    Summary
    Enables cardiolipin binding activity and magnesium ion transmembrane transporter activity. Involved in mitochondrial magnesium ion transmembrane transport. Located in mitochondrion. Is active in mitochondrial inner membrane. Used to study Barth syndrome. Orthologous to human MRS2 (magnesium transporter MRS2). [provided by Alliance of Genome Resources, Nov 2024]
