CC -!- FUNCTION: Processively dephosphorylates 'Ser-2' and 'Ser-5' of the
CC heptad repeats YSPTSPS in the C-terminal domain of the largest RNA
CC polymerase II subunit (RPB1). This promotes the activity of RNA
CC polymerase II. {ECO:0000269|PubMed:15170348}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] +
