Probable transporter; part of the gene cluster that mediates the biosynthesis of enfumafungin, a glycosylated fernene-type triterpenoid with potent antifungal activity, mediated by its interaction with beta-1,3-glucan synthase and the fungal cell wall (PubMed:30051576). Might be involved in transport of enfumafungin to and across organelle membranes (Probable). Belongs to the OSBP family.
