NeuroD, also called Beta2, is a basic helix loop helix transcription factor expressed in certain parts of brain, beta pancreatic cells and enteroendocrine cells. It is involved in the differentiation of nervous system and development of pancreas. It heterodimerizes with the products of E2A gene and controls the transcription of a variety of genes by identifying and binding E boxes in their promoter region.

There are two types of this factor:

• NeuroD1
  NEUROD1
  Neurogenic differentiation 1 , also called β2 is a transcription factor of the NeuroD-type. It is encoded by the human gene NEUROD1.It is a member of the NeuroD family of basic-helix-loop-helix transcription factors...
