ABC transporter; part of the gene cluster that mediates the biosynthesis of the mycotoxin cyclochlorotine, a hepatotoxic and carcinogenic cyclic chlorinated pentapeptide (PubMed:26954535). With the MFS transporter cctQ, is most likely responsible for cyclochlorotine secretion and thereby may contribute to intrinsic resistance (PubMed:26954535). Mycotoxin biosynthesis. Belongs to the ABC transporter superfamily.
