HMDB Protein ID HMDBP11650
Secondary Accession Numbers None
Name Carboxy-terminal domain RNA polymerase II polypeptide A small phosphatase 2
  1. Nuclear LIM interactor-interacting factor 2
  2. Protein OS-4
  3. Small C-terminal domain phosphatase 2
  4. Small CTD phosphatase 2
  5. NLI-interacting factor 2
  6. SCP2
Gene Name CTDSP2
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Preferentially catalyzes the dephosphorylation of 'Ser-5' within the tandem 7 residues repeats in the C-terminal domain (CTD) of the largest RNA polymerase II subunit POLR2A. Negatively regulates RNA polymerase II transcription, possibly by controlling the transition from initiation/capping to processive transcript elongation. Recruited by REST to neuronal genes that contain RE-1 elements, leading to neuronal gene silencing in non-neuronal cells. May contribute to the development of sarcomas.
