Abstract

Since its discovery in 1985, the function of the C-terminal domain (CTD) of RNA polymerase II has been a puzzle. Recent studies suggest that the CTD functions as a linear platform for assembly of complexes that splice, cleave and polyadenylate pre-mRNA. A new set of CTD-associated SR-like proteins (CASPs) have been implicated in pre-mRNA processing and transcription elongation as a component of the emerging 'transcriptosome'.
