Elsinochromes biosynthesis cluster-specific transcription factor that positively regulates the expression of cluster genes including RDT1, PKS1, PRF1 and HP1, and subsequent elsinochromes production. Expression is induced by the presence of the cluster-specific polyketide synthase PKS1 (PubMed:18957608). Expression is up-regulated during nitrogen starvation or at alkaline pH, but repressedin the presence of large amounts of glucose (PubMed:18957608). Blocks the expression of the elsinochrome cluster genes RDT1, PKS1, PRF1 and HP1, and impairs the production of elsinochrome.
