General description

RNA binding protein fox-1 homolog 3 (UniProt: Q8BIF2; also known as Fox-1 homolog C, Hexaribonucleotide-binding protein 3, Fox-3, Neuronal nuclei antigen, NeuN antigen) is encoded by the Rbfox3 (also known as D11Bwg0517e, Hrnbp3) gene (Gene ID: 52897) in murine species. Fox-3 acts as a pre-mRNA alternative splicing regulator. It regulates alternative splicing of RBFOX2 to enhance the production of mRNA species that are targeted for nonsense-mediated decay (NMD). It is widely expressed in brain, including in cerebral cortex, hippocampus, thalamus, caudate/putamen, cerebellum, and in the spinal cord (at protein level). However, Purkinje cells lack Fox-3 expression. It is also found in the retina in the ganglion cells and some cells in the inner nuclear layer, but is absent from the photoreceptor cells and most cells in the inner nuclear layer. In developing mouse it is expressed in the neural tube as early as day E9.5. Fox-3 expression is shown to be up-regulated by retinoic acid in p19 cells during neural differentiation. Knockout mice display significantly reduced brain weight, impaired neurofilament expression and decreased white matter volume, but normal total body mass. Five isoforms of Fox-3 have been described that are generated by alternative splicing.

Specificity

This antibody recognizes Fox-3 at the N-terminus.

Immunogen

Epitope: N-terminus
GST-tagged recombinant protein corresponding to the N-terminus of mouse Fox-3.

Application

Anti-Fox-3, Cat. No. ABN51, is a highly specific rabbit polyclonal antibody that targets Fox 3/NeuN and has been tested in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Annexin A2 (AnxA2) is a multi-functional and -compartmental protein whose subcellular localisation and functions are tightly regulated by its post-translational modifications. AnxA2 and its Tyr23-phosphorylated form (pTyr23AnxA2) are involved in malignant cell transformation, metastasis and angiogenesis. Here, we show that
