ABCB6


ATP-binding cassette super-family B member 6, mitochondrial is a protein that in humans is encoded by the ABCB6 gene.
The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies. This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance as well as antigen presentation. This half-transporter likely plays a role in mitochondrial function. Localized to 2q26, this gene is considered a candidate gene for Dyschromatosis Universalis Hereditaria, a disorder of skin pigment metabolism. The protein also carries the Lan antigen, which defines the Lan blood group system.
