UniProt Summary: 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. {ECO:0000269|PubMed:17643375, ECO:0000269|PubMed:22137580, ECO:0000269|PubMed:24997600}.
