Transcription factor that regulates asexual reproduction (PubMed:24161731). 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). Expression is regulated by the upstream regulator ada1 (PubMed:24161731). Results in near absence of conidia production (PubMed:24161731). Belongs to the EFG1/PHD1/stuA family.
