Background Information
The mature 3-prime ends of cellular mRNAs are producted by endonucleolytic cleavage of the primary transcripts, followed by polyadenylation of the upstream cleavage products. The cleavage and polyadenylation specificity factor (CPSF) has a essential role in pre-mRNA 3-prime end processing in that it is required in both the cleavage step and subsequent poly(A) addition [PMID: 9651582]. CPSF4 is a component of the cleavage and polyadenylation specificity factor (CPSF) complex, whose other components are CPSF1, CPSF2, CPSF3 and FIP1L1.
