[5] The product of the ABCB11 gene is an ABC transporter named BSEP (bile salt export pump), or sPgp (sister of P-glycoprotein).

ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White).

This particular protein is responsible for the transport of taurocholate and other cholate conjugates from hepatocytes (liver cells) to the bile.
