PrecautionsCTDSP1 Antibody (internal region) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Synonyms NIF3, NLIIF, SCP1
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.
Cellular Location Nucleus. Note=Colocalizes with RNA polymerase II
Tissue Location Expression is restricted to non-neuronal tissues. Highest expression in skeletal muscle, spleen, lung and placenta.
