Source Description
UniProtAtypical and probable non DNA-binding bHLH transcription factor that regulates light-mediated responses in day light conditions by binding and inhibiting the activity of the bHLH transcription factor HFR1, a critical regulator of light signaling and shade avoidance. Forms non-functional heterodimers with HFR1, causing liberation and activation of PIF4 from the transcriptionally inactive HFR1-PIF4 complex. {ECO:0000269|PubMed:16786307, ECO:0000269|PubMed:23224238}.
