| Function |
Drug efflux transporter present in a number of stem cells that acts as a regulator of cellular differentiation. Able to mediate efflux from cells of the rhodamine dye and of the therapeutic drug doxorubicin. Specifically present in limbal stem cells, where it plays a key role in corneal development and repair. {ECO:0000269|PubMed:12960149, ECO:0000269|PubMed:15205344, ECO:0000269|PubMed:15899824, ECO:0000269|PubMed:22306008}.

| Subcellular Location |
Cell membrane {ECO:0000269|PubMed:12960149}; Multi-pass membrane protein {ECO:0000255|PROSITE-ProRule:PRU00441, ECO:0000269|PubMed:12960149}.

| Tissue Specificity |
Expressed by CD133-expressing progenitor cells among epidermal melanocytes (at protein level). Widely expressed with specific expression in pigment cells. Highly expressed in several malignant tissues: highly expressed in clinical melanomas, with low expression in normal skin. In melanoma, marks malignant melanoma-initiating cells (MMIC), in which clinical virulence resides as a consequence of unlimited self-renewal capacity, resulting in inexorable tumor progression and metastasis. Also highly expressed in a number of leukemia cells. Expressed in basal limbal epithelium. {ECO:0000269|PubMed:12960149, ECO:0000269|PubMed:15760339, ECO:0000269|PubMed:22044138, ECO:0000269|PubMed:22675422, ECO:0000269|PubMed:22784549, ECO:0000269|PubMed:23770371, ECO:0000269|PubMed:24934811, ECO:0000269|PubMed:25030174}.
