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 gene is a member of the MRP subfamily which is involved in multi-drug resistance.

This gene and another subfamily member are arranged head-to-tail on chromosome 16q12.1.
