ABCF2 is a gene that encodes a member of the ATP-binding cassette (ABC) transporter superfamily. ATP-binding cassette proteins transport various molecules across extra- and intracellular membranes. Alterations in this gene may be involved in cancer progression. Related pseudogenes have been identified on chromosomes 3 and 7. Diseases associated with ABCF2 include Cystic Fibrosis and Osteogenesis Imperfecta, Type I.
