Target Background

Function
RNA-binding protein that regulates alternative splicing events by binding to 5'-UGCAUGU-3' elements. Prevents binding of U2AF2 to the 3'-splice site. Regulates alternative splicing of tissue-specific exons and of differentially spliced exons during erythropoiesis. RNA-binding protein that seems to act as a coregulatory factor of ER-alpha.
Gene References into Functions
  1. Rbfox2 nonsense mutation is associated with hypoplastic left heart syndrome. PMID: 27485310
  2. Data show that while RBFOX1 and RBFOX2 do not mediate neuron-specific processing of UBE3A-ATS, these proteins play important roles in developing neurons and are not completely functionally redundant. PMID: 27146458
  3. Results showed that the expression patterns of these genes were indicative of the onset of EMT in in-vitro models, but not in tissue samples. However, the ratio between ESRP1 or ESRP2 and RBFOX2 significantly decreased during EMT and positively correlated with the EMT-specific phenotype in cell models. Low ESRP1/RBFOX2 ratio value was associated with a higher risk of metastasis in early breast cancer patients. PMID: 27911856
  4. Rbfox2 modulates the functions of vascular CaV1.2 calcium channel by dynamically regulating the expressions of alternative exons 9* and 33, which in turn affects the vascular myogenic tone. PMID: 28993448
  5. RBFOX2 dysregulation by dominant-negative RBFOX2 is an early pathogenic event in diabetic hearts. PMID: 27239029
  6. RBFox2 interactis with chromatin in a nascent RNA-dependent manner. RBFox2 inactivation eradicates PRC2 targeting on the majority of bivalent gene promoters and leads to transcriptional de-repression. PMID: 27211866
  7. Some of the widespread cellular functions of Rbfox2 protein are attributable to regulation of miRNA biogenesis, and might include the mis-regulation of miR-20b and miR-107 in cancer and neurodegeneration. PMID: 27001519
  8. RBFOX proteins can facilitate the splicing of micro-exons. We also found that PTBP1 likely regulates the inclusion of micro-exons, possibly by repressing the inclusion of micro-exons that are enhanced by RBFOX proteins and other splicing factors.[RBFOX] PMID: 25524026
  9. CPSF2 and SYMPK, are RBFOX2 cofactors for both inclusion and exclusion of internal exons. PMID: 25921069
  10. RBFOX2 SNPs showed evidence for effects across multiple reading and language traits. PMID: 25065397
  11. Results show that the conserved Rbfox2 RNA binding protein regulates 30% of the splicing transitions observed during myogenesis and is required for the specific step of myoblast fusion. PMID: 25087874
  12. MBNL1 and RBFOX2 cooperate to establish a splicing programme involved in pluripotent stem cell differentiation. PMID: 24048253
  13. RBFOX2 polymorphism is associated with breast cancer. PMID: 23143756
  14. RBFOX2 drives mesenchymal tissue-specific splicing in both normal and cancer tissues. PMID: 23149937
  15. FOX-2 is involved in splicing of ataxin-2 transcripts and that this splicing event is altered by overexpression of ataxin-1 PMID: 22666429
  16. functional significance of EMT-associated alternative splicing depletion of RBFOX2 in mesenchymal cells PMID: 21876675
  17. This study characterizes the mechanism by which RBFOX2 regulates protein 4.1R exon 16 splicing through the downstream intronic element UGCAUG. PMID: 22083953
  18. the negative regulation of Rbfox2 by Rbfox3 through a novel mechanism PMID: 21747913
  19. Fox-2 plays an integral role in the regulation of LH2 splicing and knockdown of Fox-2 may suggest a novel approach to strategies directed against scleroderma. PMID: 20131247
  20. Fox-1 and Fox-2 isoforms specifically activate splicing of neuronally regulated exons, which requires UGCAUG enhancer elements PMID: 16260614
  21. Fox-1 and Fox-2 splicing factors have roles in alternative splicing of protein 4.1R PMID: 16537540
  22. Fox-1/Fox-2 proteins block prespliceosome complex formation at two distinct steps through binding to two functionally important UGCAUG elements. PMID: 18573872
  23. These results establish hnRNP H and hnRNP F as being repressors of exon inclusion and suggest that Fox proteins enhance their ability to antagonize ASF/SF2. PMID: 18573884
  24. predict thousands of Fox-1/2 targets with conserved binding sites, at a false discovery rate of approximately 24%, including many validated experimentally, suggesting a surprisingly extensive splicing regulatory networks PMID: 18794351
  25. These findings suggest that FOX2 functions as a critical regulator of a splicing network, and that FOX2 is important for the survival of human embryonic stem cells. PMID: 19136955
