MFS transporter; part of the gene cluster that mediates the biosynthesis of cercosporin, a light-activated, non-host-selective toxin (By similarity). The perylenequinone chromophore of cercosporin absorbs light energy to attain an electronically-activated triplet state and produces active oxygen species such as the hydroxyl radical, superoxide, hydrogen peroxide or singlet oxygen upon reaction with oxygen molecules (PubMed:11701851). These reactive oxygen species cause damage to various cellular components including lipids, proteins and nucleic acids (PubMed:11701851). Responsible for secretion and accumulation of cercosporin, but does not play any roles in self-protection against the toxicity of cercosporin (By similarity). Belongs to the major facilitator superfamily. CAR1 family.
