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. 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].
