Human Mitoferrin-2, SLC25A28 ELI

Mitochondrial iron transporter that mediates iron uptake.

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 (By similarity).
