Phosphatase Classification: FCP:SCP
Introduction
SCP is named after Small CTD (carboxy-terminal domain, RNA polymerase II, polypeptide A) phosphatase. This subfamily has three members in human, SCP1 (or CTDSP1), SCP2 (or CTDSP2), and SCP3 (or CTDSPL). They are present in neuronal progenitor cells and nonneuronal cells and targets neuronal genes by interacting with the REST/NRSF complext. The SCP1 is a transcriptional corepressor for inhibiting neuronal gene transcription in non-neuronal cells. For its molecular function, the SCP1 prefers to dephosphorylate pSer5 at CTD [1].
