Function
PCF11_YEAST Component of the cleavage factor IA (CFIA) complex, which is involved in the endonucleolytic cleavage during polyadenylation-dependent pre-mRNA 3'-end formation and cooperates with cleavage factor NAB4/CFIB and the cleavage and polyadenylation factor (CPF) complex. Independently involved in RNA polymerase II transcript termination. Binds RNA. Seems to bridge RNA polymerase II and the native transcript and may be involved in dismantling the RNA polymerase II elongation complex.[1] [2]

Publication Abstract from PubMed
During transcription, RNA polymerase (Pol) II synthesizes eukaryotic messenger RNA. Transcription is coupled to RNA processing by the carboxy-terminal domain (CTD) of Pol II, which consists of up to 52 repeats of the sequence Tyr 1-Ser 2-Pro 3-Thr 4-Ser 5-Pro 6-Ser 7 (refs 1, 2). After phosphorylation, the CTD binds tightly to a conserved CTD-interacting domain (CID) present in the proteins Pcf11 and Nrd1, which are essential and evolutionarily conserved factors for polyadenylation-dependent and -independent 3'-RNA processing, respectively. Here we describe the structure of a Ser 2-phosphorylated CTD peptide bound to the CID domain of Pcf11. The CTD motif Ser 2-Pro 3-Thr 4-Ser 5 forms a beta-turn that binds to a conserved groove in the CID domain. The Ser 2 phosphate group does not make direct contact with the CID domain, but may be recognized indirectly because it stabilizes the beta-turn with an additional hydrogen bond. Iteration of the peptide structure results in a compact beta-spiral model of the CTD. The model suggests that, during the mRNA transcription-processing cycle, compact spiral regions in the CTD are unravelled and regenerated in a phosphorylation-dependent manner.
