Anti-NEUROD1 antibodies are used in the immunodetection of the protein neuronal differentiation 1. In humans, the canonical protein has a reported length of 356 amino acid residues and a mass of 39.9 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably expressed in many tissues, such as the caudate, urinary bladder, and bone marrow. NEUROD1 is known to act as a transcriptional activator: mediates transcriptional activation by binding to E box-containing promoter consensus core sequences 5'-CANNTG-3'. Post-translational modifications have been described, including phosphorylation. NEUROD1 is also used as a cellular marker for characterizing neuronal cells. Synonyms for this target antigen include BHF-1, MODY6, NEUROD, T2D, bHLHa3, and BETA2. NEUROD1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
