HMDB Protein ID HMDBP11917
Secondary Accession Numbers None
Name Putative RNA polymerase II subunit B1 CTD phosphatase RPAP2
  1. RNA polymerase II-associated protein 2
Gene Name RPAP2
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function 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.
