Mitoferrin-1; Mitochondrial iron transporter that specifically mediates iron uptake in developing erythroid cells, thereby playing an essential role in heme biosynthesis. 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); Belongs to the mitochondrial carrier (TC 2.A.29) family.

Solute carrier family 25 member 28; Belongs to the mitochondrial carrier (TC 2.A.29) family.

Metalloreductase STEAP3; Endosomal ferrireductase required for efficient transferrin- dependent iron uptake in erythroid cells. Participates in erythroid iron homeostasis by reducing Fe(3+) to Fe(2+). Also mediates reduction of Cu(2+) to Cu(1+), suggesting that it participates in copper homeostasis. Uses NADP(+) as acceptor. Indirectly involved in exosome secretion by facilitating the secretion of proteins such as TCTP (By similarity). May play a role downstream of p53/TP53 to interface apoptosis and cell cycle progression.

Transmembrane protein 14C; Required for normal heme biosynthesis; Belongs to the TMEM14 family.

Feline leukemia virus subgroup C cellular receptor 1.

Protoporphyrinogen oxidase; Catalyzes the 6-electron oxidation of protoporphyrinogen-IX to form protoporphyrin-IX.

5-aminolevulinate synthase, erythroid-specific, mitochondrial.

Uroporphyrinogen III synthase.

Mitochondrial glycine transporter; Mitochondrial glycine transporter that imports glycine into the mitochondrial matrix. Plays an important role in providing glycine for the first enzymatic step in heme biosynthesis, the condensation of glycine with succinyl-CoA to produce 5-aminolevulinate (ALA) in the mitochondrial matrix. Required during erythropoiesis. Belongs to the mitochondrial carrier (TC 2.A.29) family. SLC25A38 subfamily.
