NR1D2 can interact with NCOA5 coactivator, leading to a strong increase of transcription of target genes. NR1D2 also binds to the sequences 5'-AATGTAGGTCA-3' and 5'-ATAACTAGGTCA-3' and acts as a potent competitive transcriptional silencer and negative regulator of RORalpha mediated trans-activation. NR1D2 may play different roles in metabolism, inflammation, and circadian cycling in the organ-specific manner in homeostasis.
