For example, RBBP6 has been identified as a critical factor in activating the cleavage and polyadenylation specificity factor (CPSF), which is essential for the proper processing of mRNA[3][5].
The extent of human eukaryotic translation initiation factor eIF3 interaction with the 3' ends of mRNA 3' untranslated regions (3'-UTRs) correlates with the level of translation.
