 Abstract: Concomitant with RNA polymerase II (Pol II) transcription, RNA maturation factors are recruited to the carboxyl-terminal domain (CTD) of Pol II, whose phosphorylation state changes during a transcription cycle. CTD phosphorylation triggers recruitment of functionally different factors involved in RNA processing and transcription termination; most of these factors harbor a conserved CTD interacting domain (CID). Orchestration of factor recruitment is believed to be conducted by CID recognition of distinct phosphorylated forms of the CTD. We show that the human RNA processing factor SCAF8 interacts weakly with the unphosphorylated CTD of Pol II. Upon phosphorylation, affinity for the CTD is increased; however, SCAF8 is promiscuous to the phosphorylation pattern on the CTD. Employing a combined structural and biophysical approach, we were able to distinguish motifs within CIDs that are involved in a generic CTD sequence recognition from items that confer phospho-specificity.
