Required for asexual sporulation and normal colony development. May be involved in brlA activation. Could play a regulatory role in controlling the flug-initiated signal transduction pathway that triggers the asexual reproduction. Present throughout the asexual cycle. The fungal-differentiation regulator (Fungal-DR) domain is only found in fungal regulator of G-protein signaling (RGS) proteins that regulate differentiation pathways. It is required for function (By similarity).
