ATP-binding cassette sub-family F member 2 is a protein that in humans is encoded by the ABCF2 gene. Function The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intracellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, and White). This protein is a member of the GCN20 subfamily. Alternative splicing of this gene results in multiple transcript variants. ABCF2 acts as a suppressor of the volume-sensitive outwardly rectifying Cl channel (CLCN3).
