ABC-type transporter; part of the gene cluster that mediates the biosynthesis of the meroterpenoid compound andrastin A, a promising antitumoral compound (PubMed:28529508). Is required for the production of andrastin A but does not have a significant role in its secretion (PubMed:28529508). Drastically reduces the production of andrastin A but does not affect its secretion. Belongs to the ABC transporter superfamily. ABCG family. PDR (TC 3.A.1.205) subfamily.
