Transcription factor; part of the DMATS1 gene cluster that mediates the biosynthesis of a reversely N-prenylated monomeric L-tryptophan (r-N-DMAT) (PubMed:28295904). Seems not to regulate the expression of the DMATS1 cluster (PubMed:28295904). Expression is negaticely regulated by the global nitrogen regulator areA. Does not affect the expression of expression of DMATS1, FFUJ_09176,and FFUJ_09178; nor the metabolite production.
