WebThese elements are recognized by CSTF2/CstF-64, the RRM-containing subunit of the Cleavage Stimulation Factor complex . Consistent with the fundamental importance of CPA, its dysregulation is associated with a wide range of genetic disorders. ... We speculate that the interaction of CPSF and CstF with each individual sequence and with each ... 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 ...

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.
