CTDSP1

Gene
CTDSP1
Protein
Carboxy-terminal domain RNA polymerase II polypeptide A small phosphatase 1
Organism
Homo sapiens
Length
261 amino acids
Function
Preferentially catalyzes the dephosphorylation of 'Ser-5' within the tandem 7 residue 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.
