ATP-dependent transporter located in the mitochondrial inner membrane that catalyzes the export of biliverdin from the mitochondrial matrix, and plays a crucial role in hemoglobin synthesis and antioxidative stress (PubMed:22085049, PubMed:28315685, PubMed:28808058, PubMed:34011630, PubMed:37041204). Participates in the early step of the heme biosynthetic process during insertion of iron into protoporphyrin IX (PPIX) (PubMed:22085049, PubMed:28808058). Involved in the stabilization of the iron transporter mitoferrin- 1/SLC25A37 (By similarity). In addition may be involved in mitochondrial unfolded protein response (UPRmt) signaling pathway, although ABCB10 probably does not participate in peptide export from mitochondria (PubMed:28315685). {ECO:0000250|UniProtKB:Q9JI39, ECO:0000269|PubMed:22085049, ECO:0000269|PubMed:28315685, ECO:0000269|PubMed:28808058, ECO:0000269|PubMed:34011630, ECO:0000269|PubMed:37041204}. This is the function of Ensembl gene identifier ENSG00000135776 (ABCB10, ATP binding cassette subfamily B member 10).
