WebWhen CstF and CPSF bind to their respective polyadenylation signal sequences, CstF activates CPSF. The CPSF protein cleaves the pre-mRNA 10-35 nucleotides downstream (farther towards the 3’ end) from the 5’-AAUAAA-3’ sequence. This free 3’ end of the pre-mRNA is then available for the addition of adenine nucleotides.

WebNov 2, 2024 · No cleavage activity was observed when the SV40 pre-mRNA was incubated with CPSF alone. Addition of CStF and CFIIm, either individually or together, failed to … WebFractionation of HeLa cell nuclear extract resulted in the purification of two protein complexes: cleavage and polyadenylation specificity factor (CPSF) and cleavage stimulatory factor (CstF). These proteins together recognize AAUAAA and GU-rich DSEs on synthetic RNA substrates and act to promote RNA cleavage between these cis elements. WebHowever, as discussed above, our data rule out models in which the trigger to terminate is delivered during a zero order CPSF-CstF capture event, because an antisense to the poly(A) signal, placed far downstream, aborts the first order termination process (Fig. 4D, solid line). Thus, we are driven to the view that the final triggering event ... floating feeling in my head

As symplekin links CstF to CPSF (Takagaki and Manley 2000), our results indicate that CstF64 may interact with CPSF more strongly; thus, the CstF64-containing CstF complexes may be recruited to the mRNA 3′ processing complex more efficiently than the CstF64τ-containing CstF complexes. This may lead to func- floating feces

"WebSep 24, 2024 · The enzyme CPSF is responsible for the cleavage, which occurs 10–30 nucleotides downstream of its binding site. This location typically contains the polyadenylation signal sequence AAUAAA on the RNA, however variations exist that bind CPSF less strongly. Two more proteins, CstF and CFI, give specificity to the RNA … " - Cstf and cpsf
