General Information

Term

mRNA cleavage and polyadenylation specificity factor complex

ID (Ontology)

GO:0005847 (Gene Ontology)

Definition

A multisubunit complex that binds to the canonical AAUAAA hexamer and to U-rich upstream sequence elements on the pre-mRNA, thereby stimulating the otherwise weakly active and nonspecific polymerase to elongate efficiently RNAs containing a poly(A) signal.[ PubMed:14749727 ]
