EGR2 is an early growth response protein which is a group of amino acids, it is a transcription regulatory factor and is expressed in the neural crest derived cells of the cranial ganglion.
Early growth response protein 2 is a protein that in humans is encoded by the EGR2 gene. Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. EGR2 (also termed Krox20) is a transcription regulatory factor, containing three zinc finger DNA-binding sites, and is highly expressed in a population of migrating neural crest cells. It is later expressed in the neural crest derived cells of the cranial ganglion.
