GO:0005847,CC,"mRNA cleavage and polyadenylation specificity factor complex","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.",IDA

GO:0006379,BP,"mRNA cleavage","Any process in which a pre-mRNA or mRNA molecule is cleaved at specific sites or in a regulated manner.",IDA
GO:0006398,BP,"mRNA 3'-end processing by stem-loop binding and cleavage","Any mRNA 3'-end processing that involves the binding to and cleavage of a stem-loop structure. For example, histone mRNAs contain a highly conserved stem-loop sequence at the 3' end of the mRNA with a 6 base pairs (bp) stem and a 4-nt loop. The mRNA is cleaved between these two elements, after the fourth or fifth nucleotide, which is typically an adenosine.",ISS
