RNA processing is determined by phosphorylation patterns in the C-terminal repeat domain (CTD) of the RNA polymerase II. Explain in a mechanistic manner how a deficiency in the enzyme CTDK-1 affects RNA processing.
Homework Answers
There are many kinases in saccharomyces cerevisiae that phosphorylate the CTD of Rna polymerase II. CTD is essential and it has vital functions in initiation and elongation of transcription as well as in processing of MRna. The function of the CTD in these different processes appeares connected to phosphorylation of CTD, which changes through transcriptionery cycle. In saccharomyces cerevisiae, four enzymes are thre for CTD kinase activity. That os, Kin28- Ccl1, Srb10- Srb 11, CTDK-1, and Sgv1/Bur1 /Bur2. CTDK-1 is responsible for proper processing of a subset of yeast transcripts.

B. The C-terminal domain (CTD) of RNA polymerase II has a repeating structure. Phosphates can be attached to serine residues within the repeats. What are the various roles that CTD phosphorylation can play? How might the repeating nature of the CTD be important for those roles? How can you test your ideas experimentally? Cite your work
