WebCPSF binds to the AAUAAA signal and AstF binds to GU/U rich region. 3. Cleavage occurs with additional cleavage factors create 3’ end. 4. PAP to add ~200 A nucleotides to the 3’ end. 5. Poly-A binding protein to aid polyadenylation and protect RNA from degradation. CstF – cleavage stimulation factor CPSF – cleavage and polyadenylation ... CPSF is a protein complex, consisting of four proteins: CPSF-73, CPSF-100, CPSF-30 and CPSF-160. CPSF-73 is a zinc-dependent hydrolase which cleaves the mRNA precursor just downstream the polyadenylation signal sequence AAUAAA. CPSF-160 is the largest subunit of CPSF and directly binds to the AAUAAA … See more Cleavage and polyadenylation specificity factor (CPSF) is involved in the cleavage of the 3' signaling region from a newly synthesized pre-messenger RNA (pre-mRNA) molecule in the process of gene transcription. … See more • CPSF1, CPSF2, CPSF3, CPSF4, CPSF6 See more • See more
