Acts as a transcriptional regulator. Acts as a negative regulator of receptor-dependent signaling pathways. Specifically inhibits transactivation of the nuclear receptor with whom it interacts. Inhibits transcriptional activity of NEUROD1 on E-box-containing promoter by interfering with the coactivation function of the p300/CBP-mediated trancription complex for NEUROD1.
Liver. Low levels of expression were detected in heart and pancreas.
Involvement in disease
Belongs to the nuclear hormone receptor family. NR0 subfamily.
Arginine methylation by PRMT5 enhances repression activity of metabolic genes in liver in response to bile acid signaling, by increasing interaction with cofactors.
Nucleus. Cytoplasm. Colocalizes with NEUROD1 in the nucleus.
