The RNA polymerase C-terminal domain: a new role in spliceosome assembly.
Work over the last two decades has provided a wealth of data indicating that the RNA polymerase II transcriptional machinery can play an important role in facilitating the splicing of its transcripts. In particular, the C-terminal domain of the RNA polymerase II large subunit (CTD) is central in the coupling of transcription and splicing. While this has long been assumed to involve physical interactions between splicing factors and the CTD, few functional connections between the CTD and such factors have been established. We recently used a biochemical approach to identify a splicing factor that interacts directly with the CTD to activate splicing and, in doing so, may play a role in the process of spliceosome assembly.
