Drogat J and Hermand D (2012) Gene-specific requirement of RNA polymerase II CTD phosphorylation. Mol Microbiol 84(6):995-1004
Abstract: The largest subunit of RNA polymerase II, Rpb1, contains an unusual C-terminal domain (CTD) composed of numerous repeats of the YSPTSPS consensus sequence. This sequence is the target of post-translational modifications such as phosphorylation, glycosylation, methylation and transitions between stereoisomeric states, resulting in a vast combinatorial potential referred to as the CTD code. In order to gain insight into the biological significance of this code, several studies recently reported the genome-wide distribution of some of these modified polymerases and associated factors in either fission yeast (Schizosaccharomyces pombe) or budding yeast (Saccharomyces cerevisiae). The resulting occupancy maps reveal that a general RNA polymerase II transcription complex exists and undergoes uniform transitions from initiation to elongation to termination. Nevertheless, CTD phosphorylation dynamics result in a gene-specific effect on mRNA expression. In this review, we focus on the gene-specific requirement of CTD phosphorylation and discuss in more detail the case of serine 2 phosphorylation (S2P) within the CTD, a modification that is dispensable for general transcription in fission yeast but strongly affects transcription reprogramming and cell differentiation in response to environmental cues. The recent discovery of Cdk12 as a genuine CTD S2 kinase and its requirement for gene-specific expression are discussed in the wider context of metazoa.CI - (c) 2012 Blackwell Publishing Ltd.
