Transcription factor that regulates asexual reproduction (PubMed:1516832, PubMed:8722771, PubMed:9312029, PubMed:25550299). Binds the StuA-response elements (StRE) with the consensus sequence 5'-(A/T)CGCG(T/A)N(A/C)-3' at the promoters of target genes (PubMed:9312029, PubMed:25359270). Required from the very earliest events of asexual reproduction until completion of conidiophore development, but is not specifically required for differentiation of conidia (PubMed:1516832). Represses transcription of the abaA developmental regulatory gene and of the developmentally regulated awh11 gene (PubMed:9312029). Controls the expression of the catalase-peroxidase gene cpeA (PubMed:12455692). Plays an important role in cell wall biogenesis during the development by controlling the transcription level of fksA (PubMed:25359270). Expression is increased 50-fold during the establishment of developmental competence (PubMed:1516832, PubMed:2062309, PubMed:17630328). Expression is positively controlled by brlA (PubMed:1516832). Expression is also regulated by the LAMMER kinase lkhA (PubMed:23516554). Leads to defective conidiophore morphology and impairs conidia production (PubMed:25550299). Affects cell wall beta-1,3-glucan biosynthesis (PubMed:25359270). Belongs to the EFG1/PHD1/stuA family.
