Target Background

Function
Component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. CPSF4 binds RNA polymers with a preference for poly(U).
Gene References into Functions
  1. The authors define the molecular architecture of the core human CPSF complex comprising CPSF160, WDR33, CPSF30 and Fip1 and identify specific domains involved in inter-subunit interactions. Together, these results shed light on the function of CPSF in mediating polyA signal-dependent RNA cleavage and polyadenylation. PMID: 29274231
  2. Residues F103 and M106 within the NS1-CPSF4 binding region are important for viral replication. PMID: 28554059
  3. Cleavage and polyadenylation specific factor 4 targets NF-kappaB/cyclooxygenase-2 signaling to promote the growth and survival of non-small cell lung carcinoma cells. PMID: 27450326
  4. These findings support a role for iron in some zinc-finger proteins. Using electrophoretic mobility shift assays and fluorescence anisotropy, we report that CPSF30 selectively recognizes the AU-rich hexamer (AAUAAA) sequence present in pre-mRNA, providing the first molecular-based evidence to our knowledge for CPSF30/RNA binding. PMID: 27071088
  5. unexpectedly found that CPSF subunits CPSF30 and Wdr33 directly contact AAUAAA PMID: 25301780
  6. CPSF4 upregulates human TERT promoter activity, human TERT expression and telomerase activity. PMID: 24618080
  7. Data show that 4 drug-like compounds from traditional Chinese Medicine (TCM) database were selected as potential inhibitors for the cleavage and polyadenylation specific factor CPSF30-binding site of influenza A virus of non-structural protein 1 (NS1A). PMID: 24562912
  8. CPSF4 plays a critical role in regulating lung cancer cell proliferation and survival and may be a potential prognostic biomarker and therapeutic target for lung adenocarcinoma. PMID: 24358221
  9. Data show that the NS1A protein of the pathogenic H5N1 influenza A/Hong Kong/483/97 (HK97) virus isolated from humans has an intrinsic defect in CPSF30 binding. PMID: 17522219
