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. WebIn vitro, cleavage is mediated by a protein complex that can be separated into five factors. Two of these factors are the cleavage and polyadenylation specificity factor (CPSF) …
