Neuronal splicing regulator RBFOX3 (NeuN) distribution and organization are modified in response to monosodium glutamate in rat brain at postnatal day 14.

Neuronal splicing regulator RNA binding protein, fox-1 homolog 3 (NeuN/RbFox3), is expressed in postmitotic neurons and distributed heterogeneously in the cell. During excitotoxicity events caused by the excess glutamate, several alterations that culminate in neuronal death have been described. However, NeuN/RbFox3 organization and distribution are still unknown.
