CC   -!- FUNCTION: Mitochondrial iron transporter that specifically mediates
CC       iron uptake in developing erythroid cells, thereby playing an essential
CC       role in heme biosynthesis. The iron delivered into the mitochondria,
CC       presumably as Fe(2+), is then probably delivered to ferrochelatase to
CC       catalyze Fe(2+) incorporation into protoprophyrin IX to make heme (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with ACB10; this interaction stabilizes SLC25A37 and
CC       enhances the function of SLC25A37 to import mitochondrial iron during
CC       erythroid differentiation. {ECO:0000250|UniProtKB:Q920G8}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC       Multi-pass membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the mitochondrial carrier (TC 2.A.29) family.
CC       {ECO:0000305}.
