Abstract excerpt

Phosphorylation of conserved Y₁S₂P₃T₄S₅P₆S₇ repeats in the C-terminal domain of largest subunit of RNA polymerase II (RNAPII CTD) plays a central role in the regulation of transcription and cotranscriptional RNA processing. Here, we show that Ser phosphorylation of Arabidopsis thaliana RNAPII CTD is governed by CYCLIN-DEPENDENT KINASE F;1 (CDKF;1), a unique plant-specific CTD S₇-kinase. CDKF;1 is required for in...
