A  To add N-linked oligosaccharides to glycoproteins

A  Figure 4 showing ABCB6 staining associated with human reticulocytes

B  Figure S4 detecting ABCB6 in secreted reticulocyte exosomes

C  Figure 3 showing ABCB6 expression in mature erythrocytes

D  Figure 5 showing porphyrin synthesis and ABCB6 expression in K562 cells

A  ABCB6 can be identified in exosomes of red blood cells, ABCB6 protein is found in the plasma membrane of red blood cells and the location of three other ABC proteins (7, 8 and 10), was confirmed to be localized to the mitochondria membrane

B  ABCB6 can be identified in exosomes of red blood cells and glycosylation of ABCB6 protein directs it to the mitochondria

C  ABCB6 appears to be responsible for mitochondria uptake of porphyrins and glycosylation of ABCB6 protein directs it to the mitochondria
