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.
