WebCPSF-73 and CPSF-100 together with symplekin form the other component, also known as the core cleavage complex or mCF (mammalian cleavage factor) , which catalyzes the cleavage reaction. Symplekin is a scaffold protein and also mediates interactions with CstF and other factors in the 3′-end processing machinery ( 25 – 28 ). WebMar 21, 2024 · Cleavage and polyadenylation factor (CPF/CPSF) is a multi-protein complex essential for formation of eukaryotic mRNA 3ʹ ends. CPF cleaves pre-mRNAs at a specific site and adds a poly(A) tail. The cleavage reaction defines the 3ʹ end of the mature mRNA, and thus the activity of the endonuclease is highly regulated.

WebFeb 10, 2024 · In untreated cells, PAS cleavage of both the TBP and p53 pre-mRNAs was inhibited by PCF11 depletion, as revealed by the increased ratio of uncleaved/total RNAs in PCF11-depleted cells (Fig 1E). This is consistent with the fact that this factor is essential for the co-transcriptional, Pol II-coupled PAS cleavage reaction (West et al, 2008).
