Recombinant carboxy-terminal repeat domain (CTD) of the largest subunit of RNA polymerase II expressed in E. coli. Contains tandem repeats of a heptapeptide sequence Tyr-Ser-Pro-Thr-Ser-Pro-Ser, which is highly conserved among eukaryotic organisms. The RNA pol II-CTD is essential for transcription, for organization of transcription foci within the nucleus, and for pre-mRNA processing, and is targeted by several kinases and phosphatases.
