Transcription factor that regulates asexual reproduction (PubMed:21148688). 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 the expression of the penicillin gene cluster (PubMed:21148688). Blocks conidiation and causes aberrant hyphal morphology (PubMed:21148688). Decreases expression of developmental regulators brlA and abaA (PubMed:21148688). Belongs to the EFG1/PHD1/stuA family.
