SLC25A28, MFRN2, Mitoferrin-2, Mitochondrial RNA-splicing protein 3/4 homolog, Mitochondrial iron transporter 2, Solute carrier family 25 member 28

MFRN2 is mitochondrial iron transporter that mediates iron uptake. It is probably required for heme synthesis of hemoproteins and Fe-S cluster assembly in non-erythroid cells. The iron delivered into the mitochondria, presumably as Fe(2+), is then probably delivered to ferrochelatase to catalyze Fe(2+) incorporation into protoprophyrin IX to make heme.
