Background Information

CTDSPs are C-class phosphatases that act on Ser 5 of the Pol II C-terminal domain (CTD) to decrease transcription [PMID:15681389]. CTDSP enzymatic activity is required for REST function, and knockdown of CTDSP induces the neuronal differentiation of mouse embryonic carcinoma P19 cells. CTDSP2 has been shown to enhance TGF-β signaling by the dephosphorylation of SMAD proteins and attenuates androgen receptor-mediated transcription [PMID:16724108]. It negatively regulates RNA polymerase II transcription by controlling the transition from initiation/capping to processive transcript elongation. It was recruited by REST to neuronal genes that contain RE-1 elements, leading to neuronal gene silencing in non-neuronal cells[PMID: 12721286].
