Neurogenic differentiation factor 2 (NEUROD2)

Neurogenic differentiation factor 2 (NEUROD2) is a basic helix-loop-helix (bHLH) transcription factor critically involved in the determination and maintenance of neuronal identity during development[1][6]. NEUROD2 mediates transcriptional activation from neuron-specific promoters and regulates gene networks essential for neuronal fate specification, cortical neuron migration, dendrite and synapse development, and synaptic plasticity[4][8]. It acts as a repressor of neuronal differentiation by inducing downstream targets such as ZEB1 and controlling the repression of REST expression[6]. NEUROD2 is essential for post-migratory neuronal maturation, the establishment of proper synaptic connections, and the development of several key brain regions, including the hippocampus, cortex, amygdala, and hypothalamic-pituitary axis[6][8]. Pathogenic variants of NEUROD2 are associated with early-onset epilepsy and neurodevelopmental syndromes characterized by migration defects, abnormal spine density, and impaired neuronal function[4][6]. There are currently no clinically approved drugs known to directly target NEUROD2.
