Pleiotropic ABC efflux transporter that may be involved in the modulation susceptibility to a wide range of unrelated cytotoxic compounds (Probable). Does not acts as an efflux pump for azoles, including fluconazole, itraconazole, ketoconazole, miconazole and voriconazole, nor does it modulate susceptibility to cycloheximide (PubMed:31501141). Expression is induced upon exposure to amphotericin B, the allylamine terbinafine, and the azole itraconazole. Belongs to the ABC transporter superfamily. ABCB family. Multidrug resistance exporter (TC 3.A.1.201) subfamily.
