Subcellular location [CC]Melanosome membrane {ECO:0000269|PubMed:10471510, ECO:0000269|PubMed:12643545, ECO:0000269|PubMed:16524428, ECO:0000269|PubMed:16621890, ECO:0000269|PubMed:17081065};
Multi-pass membrane protein {ECO:0000255}. Lysosome membrane {ECO:0000269|PubMed:16524428, ECO:0000269|PubMed:16621890};
Multi-pass membrane protein {ECO:0000255}. Apical cell membrane {ECO:0000269|PubMed:18828673};
Multi-pass membrane protein {ECO:0000255}. Note=Distributed throughout the endo-melanosomal system but most of endogenous protein is localized in unpigmented stage II melanosomes. Its expression on the apical cell membrane is sensitive to tyrosine (PubMed:18828673). {ECO:0000269|PubMed:18828673}.
