Anti-Fox1 Antibody, clone 1D10

RNA binding protein fox-1 homolog 1 (UniProt Q9JJ43; also known as Ataxin-2-binding protein 1, Fox-1 homolog A, Hexaribonucleotide binding protein 1) is encoded by the Rbfox1 (also known as A2bp, A2bp1, Fox-1, Hrnbp1) gene (ORF MNCb-3035; Gene ID 268859) 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. Rbfox1 transcript itself is subjected to alternative splicing in response to chronic cell depolarization. This results in the increased expression of the nuclear, splicing-active Rbfox1 isoform, which in turn leads to increased splicing of Rbfox1 target transcripts of proteins, including N-methyl D-aspartate (NMDA) receptor 1 (Grin1) and a calcium ATPase (Atp2b1), that play important roles in neuronal excitation and calcium homeostasis.
