ABC transporter; part of the gene cluster that mediates the biosynthesis of gibepyrone A, a 2H-pyran-2-one metabolite exhibiting a moderate antimicrobial activity against Gram-positive bacteria and yeasts (PubMed:27856636). GPY2 seems to have a minor impact on the efflux of gibepyrone A out of the cell, but it was shown to repress expression of the key gene GPY1 (PubMed:27856636). Members of the velvet complex, VEL1, VEL2, and LAE1, negatively affect GPY2 gene expression and gibepyrone A product formation, whereas SGE1 represents a positive regulator of gibepyrone biosynthesis. Results in a significantly enhanced level of extracellular gibepyrone A. Belongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily.
