Processing of eukaryotic pre-mRNAs is an important step for the translation of proteins. These processing events include the addition of a cap structure at the 5' terminus of the pre-mRNA, the splicing out of introns and the acquisition of a polyadenosine tail at the 3' terminus of the pre-mRNA. It has now become apparent that the RNA processing events can significantly influence each other. RNA polymerase II appears as a key player in these processes, cooperating with numerous processing factors that are involved in capping, splicing, and polyadenylation. More specifically, the carboxyterminal domain of the large subunit of the enzyme plays a critical role in coordination of the processing events. The number of interactions between the various RNA processing events identified so far reflects the complexity of these reactions. As more studies focus on these interactions, additional links and cellular partners will undoubtedly be discovered. 相似文献
