Description

General description

RNA binding protein fox-1 homolog 3 also known as NeuN (Neuronal nuclei) is encoded by the Rbfox3 (also known as D11Bwg0517e, Hrnbp3) gene (Gene ID 52897) in murine species. The RNA-binding Fox (Rbfox) family of splicing factors is comprised of three members, Rbfox1 (Fox-1 or A2BP1), Rbfox2 (Fox-2 or RBM9), and Rbfox3 (Fox-3, HRNBP3 or NeuN). Rbfox proteins regulate splicing of many neuronal transcripts (pre-mRNAs) by binding the sequence (U)GCAUG in introns flanking alternative exons. A (U)GCAUG motif that lies downstream of the alternative exon generally promotes Rbfox-dependent exon inclusion, whereas an upstream motif will usually repress exon inclusion. Originally characterized as a marker of post-mitotic neurons and named neuronal nuclei (NeuN), Rbfox3 plays a role in promoting neuronal differentiation through alternative splicing of Numb pre-mRNA during brain development. Rbfox3-knockout in mice is reported to result in defective hippocampal gene expression, defects in synaptic transmission and plasticity in the dentate gyrus, as well as increased seizure susceptibility and decreased anxiety-related behaviors. Likewise, human RBFOX3 gene mutations have been linked to neurodevelopmental delay, cognitive impairments, autistic features, and epilepsy.

Specificity

Anti NeuN antibody from rabbit is a polyclonal antibody that targets NeuN N-terminal region that ends at the start of the RNA recognition motif (RRM). The target region is present in all human, mouse, and rat spliced isoforms reported by UniProt (A6NFN3, Q8BIF2, D4A2H6, A0A0G2K2J4).

Immunogen
