The ABCC subfamily of proteins is composed of nine members in Leishmania. We report that all of these proteins have an intracellular localization and that the overexpression of at least four members, ABCC3, ABCC4, ABCC5, and ABCC7, can confer resistance to antimonials, the first-line drug against Leishmania.
