Heme transporter that regulates intracellular heme availability through the endosomal or lysosomal compartment (PubMed:18418376). In macrophages of the reticuloendothelial system, is the heme transporter for heme-iron recycling. Essential for macrophage iron homeostasis, transports heme from the phagolysosome to the cytoplasm during erythrophagocytosis (EP) (PubMed:23395172). . This is the function of ENSG00000211584 (SLC48A1, solute carrier family 48 member 1).
