Neurogenins, often abbreviated as Ngn, are a family of bHLHtranscription factors involved in specifying neuronal differentiation. The family consisting of Neurogenin-1, Neurogenin-2, and Neurogenin-3, plays a fundamental role in specifying neural precursor cells and regulating the differentiation of neurons during embryonic development. It is one of many gene families related to the atonal gene in Drosophila. Other positive regulators of neuronal differentiation also expressed during early neural development include NeuroD and ASCL1.[1]
