WebCPSF-160 also makes direct contacts with CstF-77 and weakly associates with PAP . The yeast CPSF-160 homolog Yhh1 interacts with the RNAP II CTD and binds to RNA through the middle β-propeller . Fip1 was identified more than a decade later than the above-mentioned CPSF subunits, though its yeast homolog had been known for a long time. WebPolyadenylation is essential for eukaryotic mRNA expression, and CstF-64 is a subunit of the CstF polyadenylation factor that is required for accurate polyadenylation.

We used baculovirus-mediated expression in insect cells to produce highly pure protein complexes

WebFor example, CPSF interacts with transcription pre-initiation complex, through TFIID, and potentially transfers to RNAP II carboxy-terminal domain (CTD) during transcription elongation [Citation 101, Citation 102]. Both CstF and CFIm interact with RNAPII, thereby joining transcription elongation [Citation 102–104].

Webconditions (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-
