MFS-type transporter; part of the gene cluster that mediates the biosynthesis of the antibiotic 2,4- dihydroxy-3-methyl-6-(2-oxopropyl)benzaldehyde (DHMBA) and its derivatives (PubMed:23001671). Is probably involved in the transport of the metabolites to the environment (Probable). Deletion of the conserved eukaryotic csnE deneddylase subunit of the COP9 signalosome leading to defect in protein degradation results in the activation of the silenced dba gene cluster (PubMed:23001671). Expression is positively regulated by the dba cluster specific transcription factor dbaA (PubMed:23001671). Expression is also controlled by the transcription factor flbB (PubMed:25701285). Strongly reduces the production of yellow pigmentation. Belongs to the major facilitator superfamily. Monocarboxylate porter (TC 2.A.1.13) family.
