WebMar 9, 2011 · CPSF and CstF bind to the AAUAAA hexamer and U/GU-rich sequence elements that straddle the cleavage site, respectively. These two complexes contain a total of seven polypeptides, one of which is the endonuclease responsible for cleaving the pre-mRNA (Mandel et al., 2006). However, additional factors are required for the reaction. 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 ...
WebJan 3, 2024 · Once both of these sequences have been transcribed, a protein called CPSF in humans binds the AAUAAA sequence and a protein called CstF in humans binds the … 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].
WebMar 14, 2024 · On poly(A)+ processing substrates, CSPF-160 and CstF-64 as part of the CPSF and CstF subcomplexes, bind to the polyadenylation signal sequence AAUAAA and a G/U-rich downstream element, respectively (Zhao et al., 1999). As these elements are not present in replication-dependent histone mRNAs, it will be important to define how these … 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-
