ABCA5

ATP-binding cassette, sub-family A (ABC1), member 5 is a is_associated_with::protein that in humans is encoded by the ABCA5 is_associated_with::gene.

Function
The membrane-associated protein encoded by this gene is a member of the superfamily of is_associated_with::ATP-binding cassette (ABC) transporters. ABC proteins transport various molecule across extra- and intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, and White). This encoded protein is a member of the ABC1 subfamily. Members of the ABC1 subfamily comprise the only major ABC subfamily found exclusively in multicellular is_associated_with::eukaryotes. This gene is clustered among 4 other ABC1 family members on 17q24, but neither the substrate nor the function of this gene is known. is_associated_with::Alternative splicing of this gene results in several transcript variants; however, not all variants have been fully described.

Clinical significance
Mutations in ABCA5 cause excessive hair overgrowth.
