Background: RBFOX3/NeuN

RBFOX3, also known as Neuronal nuclei (NeuN), is a 34kDa marker of post-mitotic neurons that is highly conserved  among different species.  The RBFOX family regulates alternative slicing and is encoded by three genes: RBFOX1, RBFOX2 and RBFOX3.  RBFOX3 mediates hippocampal circuitry, neurogenesis, and synaptogenesis. RBFOX3 plays a crucial role in normal synaptic function and is implicated in human neurological functions and mutations have been linked to neurodevelopmental delay, cognitive impairment, autistic features, and epilepsy.
