Carboxy-terminal domain RNA polymerase II polypeptide A small phosphatase 3; CTD small phosphatase-like protein; CTDSL_HUMAN; CTDSP-like; Ctdspl; hYA22; N-like protein; NLI-interacting factor 1; Nuclear LIM interactor-interacting factor 1; Protein YA22; RBSP3; SCP3; Small C-terminal domain phosphatase 3; Small CTD phosphatase 3.

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 (By similarity). Recruited by REST to neuronal genes that contain RE-1 elements, leading to neuronal gene silencing in non-neuronal cells.
