Function

[CPSF1_HUMAN] Component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. This subunit is involved in the RNA recognition step of the polyadenylation reaction.^[1] [CPSF4_HUMAN] Component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. CPSF4 binds RNA polymers with a preference for poly(U).^[2] ^[3] [WDR33_HUMAN] Essential for both cleavage and polyadenylation of pre-mRNA 3' ends.^[4] [CSTF3_HUMAN] One of the multiple factors required for polyadenylation and 3'-end cleavage of mammalian pre-mRNAs.

Publication Abstract from PubMed

The mammalian pre-mRNA 3'-end-processing machinery consists of cleavage and polyadenylation specificity factor (CPSF), cleavage stimulation factor (CstF), and other proteins, but the overall architecture of this machinery remains unclear. CPSF contains two functionally distinct modules: a cleavage factor (mCF) and a polyadenylation specificity factor (mPSF). Here, we have produced recombinant human CPSF and CstF and examined these factors by electron microscopy (EM). We find that mPSF is the organizational core of the machinery, while the conformations of mCF and CstF and the position of mCF relative to mPSF are highly variable. We have identified by cryo-EM a segment in CPSF100 that tethers mCF to mPSF, and we have named it the PSF interaction motif (PIM). Mutations in the PIM can abolish CPSF formation, indicating that it is a crucial contact in CPSF. We have also obtained reconstructions of mCF and CstF77 by cryo-EM, assembled around the mPSF core.
