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]
Publication Abstract from PubMed
Mammalian mRNA biogenesis requires specific recognition of a hexanucleotide AAUAAA motif in the polyadenylation signals (PAS) of precursor mRNA (pre-mRNA) transcripts by the cleavage and polyadenylation specificity factor (CPSF) complex. Here we present a 3.1-A-resolution cryo-EM structure of a core CPSF module bound to the PAS hexamer motif. The structure reveals the molecular interactions responsible for base-specific recognition, providing a rationale for mechanistic differences between mammalian and yeast 3' polyadenylation.
