ABC transporter that may provide the dual role AAL-toxin export and self-protection by allowing the fungus to evade the harmful effect of its own AAL-toxin production. Gene clusters encoding host-selective toxins (HSTs) are localized on conditionally dispensable chromosomes (CDCs), also called supernumerary chromosomes, where they are present in multiple copies. The CDCs are not essential for saprophytic growth but controls host-selective pathogenicity. Belongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily.
