  4. SCP1
  5. Small C-terminal domain phosphatase 1
  6. Small CTD phosphatase 1
Gene Name CTDSP1
Protein Type Enzyme
Biological Properties
General Function Involved in phosphatase activity
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.
