Anti-NR1D1 antibodies are used in the immunodetection of the protein nuclear receptor subfamily 1 group D member 1. In humans, the canonical protein has a reported length of 614 amino acid residues and a mass of 66.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is widely expressed across many tissue types. A member of the Nuclear hormone receptor protein family, nr1d1 is known to be a transcriptional repressor which coordinates circadian rhythm and metabolic pathways in a heme-dependent manner. Synonyms for this target antigen include REVERBA, REVERBalpha, THRA1, THRAL, ear-1, hRev, Rev-ErbAalpha, and EAR1. NR1D1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 100 citations in the literature describe the use of nr1d1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
