DESCRIPTION

Also known as NR0B2_HUMAN, NR0B2, SHP. Transcriptional regulator that acts as a negative regulator of receptor-dependent signaling pathways (By similarity). Specifically inhibits transactivation of the nuclear receptor with which it interacts (By similarity). Inhibits transcriptional activity of NEUROD1 on E-box-containing promoter by interfering with the coactivation function of the p300/CBP-mediated transcription complex for NEUROD1 (PubMed:14752053). Essential component of the liver circadian clock which via its interaction with NR1D1 and RORG regulates NPAS2-mediated hepatic lipid metabolism (By similarity). Regulates the circadian expression of cytochrome P450 (CYP) enzymes (By similarity). Represses: NR5A2 and HNF4A to down-regulate CYP2C38, NFLI3 to up-regulate CYP2A5, BHLHE41/HNF1A axis to up-regulate CYP1A2, CYP2E1 and CYP3A11, and NR1D1 to up-regulate CYP2B10, CYP4A10 and CYP4A14 (By similarity). Interacts (via N-terminus) with NEUROD1 (via N-terminus and C-terminus) (PubMed:14752053). Interacts with ID2 (PubMed:14752053). Interacts with RORG, NFIL3, NR1D1 and BHLHE41 (By similarity). Heterodimer; efficient DNA binding requires dimerization with another bHLH protein (PubMed:14752053). Interacts with RARA, RXRA, THRB, NR5A1, NR5A2, NR1I3, PPARA, PPARG and EID1 (By similarity). Interacts with HNF4A; the resulting heterodimer is transcriptionnally inactive (PubMed:28128295). Interacts with DDX3X; this interaction disrupts the interaction between HNF4 and NR0B2/SHP that forms inactive heterodimers and enhances the formation of active HNF4 homodimers (PubMed:28128295).
