    NPAS1-ARNT and NPAS3-ARNT crystal structures implicate the bHLH-PAS family as multi-ligand binding transcription factors

    Dalei Wu, Xiaoyu Su ... Fraydoon Rastinejad
    Detailed structural analysis of NPAS1-ARNT and NPAS3-ARNT complexes, and further comparisons with other bHLH-PAS protein structures, show that this family of mammalian transcription factors have distinct ligand-binding pockets within their molecular architectures.
