Protein

RNA polymerase II subunit B1 CTD phosphatase Rpap2

Gene

Rpap2

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Protein phosphatase that displays CTD phosphatase activity and regulates transcription of snRNA genes. Recognizes and binds phosphorylated 'Ser-7' of the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit POLR2A, and mediates dephosphorylation of 'Ser-5' of the CTD, thereby promoting transcription of snRNA genes.By similarity

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.
