Facts about 5'-3' exoribonuclease 2.
During transcription termination, cleavage at the polyadenylation site liberates a 5' fragment that is then processed to form the mature mRNA and a 3' fragment which remains attached to the elongating polymerase. The processive degradation of this 3' fragment at this protein can promote termination of transcription.
