WebJun 1, 2003 · The poly(A) signal is recognized by the heterotetramer CPSF, while downstream regulatory GU-rich sequences are recognized by the heterotrimeric protein complex CstF. CPSF and CstF interact with each … 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. front bang hair clip insWebconditions (Supplemental Fig. S3). 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- frontbann

"Cleavage stimulatory factor or cleavage stimulation factor (CstF or CStF) is a heterotrimeric protein, made up of the proteins CSTF1 (55kDa), CSTF2 (64kDa) and CSTF3 (77kDa), totalling about 200 kDa.
