-20°CFox1 is one of a family of 3 mammalian Fox1 homologs. Fox1 was discovered in C. elegans as a gene involved in sex determination, and the name Fox is an acronym of "Feminizing locus on X" (1). The C. elegans Fox1 protein and its 3 mammalian homologues are all about 46kD proteins and each includes a central highly conserved RRM type RNA recognition motif, which corresponds to a small ~70 amino acid structure consisting of 4 beta strands and two alpha-helices. This region is identical in all three mammalian Fox1 family proteins. An alternate name for Fox 1 is ataxin-2 binding protein 1 (A2BP1), since it was discovered in a yeast two hybrid screen using ataxin-2 as bait (2). As with the other Fox proteins, it is assumed that Fox1/A2BP1 has a role in the RNA splicing in the nervous system (3). Fox3, a protein also known as NeuN, is a widely used marker of neuronal nuclei and proximal cytoplasm (4, 5). Like Fox3, Fox1 is expressed in neuronal nuclei, but with a different pattern of expression than Fox3. For example, in the cerebellum Fox3 does not stain Purkinje neurons and Golgi neurons, but these two neuron types are stained by Fox1 antibody (6). Full length Fox1 was not used as the immunogen since the three mammalian Fox1 homologues, namely Fox1, Fox2 and Fox3, include virtually identical RRM motifs. The N-terminal region of the three molecules are much more variable in the three molecules so antibodies specific for each of the three molecules can therefore be generated. The HGNC name for this protein is RBFOX1.||Applications:|Suitable for use in Immunofluorescence and Western Blot.
