HRG1 has been identified as a cell surface and lysosomal heme transporter [2]. In addition, evidence suggests this 4TM-containing protein associates with the V-ATPase in lysosomes [1]. Recent studies confirm its lysosomal location and demonstrate that it has an important physiological function in macrophages ingesting senescent red blood cells (erythrophagocytosis), recycling heme (released from the red cell hemoglobin) from the phagolysosome into the cytosol, where the heme is subsequently catabolized to recycle the iron [3].
