  • 功能：
    One of the multiple factors required for polyadenylation and 3'-end cleavage of mammalian pre-mRNAs. This subunit is directly involved in the binding to pre-mRNAs.
  • 基因功能参考文献：
    1. hnRNP H binds to two specific G-runs in exon 5a of ACHE and activates the distal alternative 3 splice site (ss) between exons 5a and 5b. Furthermore, hnRNP H competes for binding of CstF64 to the overlapping binding sites in exon 5a, and suppresses the selection of a cryptic polyadenylation site, which additionally ensures transcription of the distal 3 ss required for the generation of AChET isoform. PMID: 28180311
    2. CstF-64 is dispensable for the expression/3'-end processing of Star-PAP target mRNAs.CstF-64 and 3'-UTR cis-element determine Star-PAP specificity for target mRNA selection by excluding poly A polymerase. PMID: 26496945
    3. CstF64, an essential polyadenylation factor, is a master regulator of 3'-UTR shortening across multiple tumour types. PMID: 25409906
    4. CstF64 is central to the function of a heat-labile factor, composed of cleavage/polyadenylation specificity factor, symplekin, and cleavage stimulation factor 64 and appears to be at least partly responsible for its cell cycle regulation. PMID: 25266659
    5. CstF64 and CstF64tau modulate one another's expression and play overlapping as well as distinct roles in regulating global alternative polyadenylation profiles. PMID: 24149845
    6. CstF64 binds to thousands of dormant intronic PASs that are suppressed, at least in part, by U1 small nuclear ribonucleoproteins PMID: 23112178
    7. CSTF2 is likely to play an important role in lung carcinogenesis and be a prognostic biomarker in the clinic. PMID: 21813631
    8. nuclear accumulation of CstF-64 depends on binding to CstF-77 not symplekin; interaction between CstF-64/CstF-64Tau and CstF-77 are important for maintenance of nuclear levels of CstF complex components and intracellular localization, stability, function PMID: 21119002
    9. The Hinge domain is necessary for CstF-64 interaction with CstF-77 and consequent nuclear localization. PMID: 19887456
    10. dynamics of the CstF-64 RNA-binding domain, both free and bound to two GU-rich RNA sequences that represent polyadenylation regulatory elements, by NMR Spectroscopy PMID: 15769465
    11. The inactivity of the RSV poly(A) site was at least in part due to poor CstF binding since tethering CstF to the RSV substrate activated polyadenylation. PMID: 18272196
    12. CstF64 (cstf2) and not other CstF subunits induced by lipopolysaccharide (LPS) in murine macrophages and changes polyA site use PMID: 16207706
    13. Describes the induction of CSTF2 in the growth phase of cells. PMID: 9736695
