BZIP-type transcription factor that functions as either an activator or a suppressor, and which contributes to the regulation of fungal growth, conidiation, cell wall integrity, and virulence (PubMed:25673695). Plays a key role in virulence against insects by mediating cell wall integrity, cell surface hydrophobicity, and adherence to hydrophobic surfaces (PubMed:25673695). Exhibits negative regulation of subtilisin proteases, but positive control of an adhesin gene (PubMed:25673695). Highly expressed during infection structure appressorium formation. Alters culture pigmentation and leads to defects in cell wall integrity, adhesion to hydrophobic surfaces, and topical infection of insects.
