ABCB5 (ATP binding cassette subfamily B member 5) gene is located in human chromosome 7p21.1. The encoded protein belongs to the subfamily B multidrug resistance and ATP-binding cassette superfamily of active transporters. The encoded protein have two identical halves, each contains a hydrophobic region with six transmembrane segments and a nucleotide-binding region. Expression of this gene is observed in prostate and testis and in human melanoma tumor-initiating cells.

ABCB5 belongs to the ATP-binding cassette (ABC) transporter superfamily of integral membrane proteins. These proteins participate in ATP-dependent transmembrane transport of structurally diverse molecules ranging from small ions, sugars, and peptides to more complex organic molecules.

ABCB5 (ATP binding cassette subfamily B member 5) is a cell surface marker for melanoma-initiating cells, on cellular metabolism. ABCB5 significantly regulates glycolysis, glutaminolysis and phospholipid metabolism. It induces stem cell differentiation, stem cell immortality and anti-apoptotic activity. The gene is upregulated in many cancer subtypes, including breast cancer. Recent studies reveal that ABCB5 is a novel marker for limbal stem cell and is needed for corneal development and repair. ABCB5 shows resistance against taxanes and anthracyclines, the anti-cancer drugs.
