Transcription factor that regulates asexual reproduction (PubMed:26283234). 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 (By similarity). Controls conidiation by positively regulating the expression of brlA and abaA (PubMed:26283234). Positively regulates the cephalosporin biosynthesis gene cluster (PubMed:26283234). Also involved hyphal fragmentation and cell wall integrity (PubMed:26283234). Blocks the conidiation through severely down-regulating the expression of brlA and abaA (PubMed:26283234). Drastically reduces cephalosporin production by decreasing expression of pcbAB, pbcC, cefD1, cefD2, cefEF and cefG (PubMed:26283234). Reduces also the expression of the mannoprotein encoding genes Acmp2 and Acmp3 and impairs cell wall integrity (PubMed:26283234). Belongs to the EFG1/PHD1/stuA family.
