Ctdspl - CTD (carboxy-terminal domain, RNA polymerase II, polypeptide A) small phosphatase-like

Predicted to enable RNA polymerase II CTD heptapeptide repeat phosphatase activity. Acts upstream of or within negative regulation of G1/S transition of mitotic cell cycle and negative regulation of protein phosphorylation. Predicted to be located in nucleus. Is expressed in several structures, including adipose tissue; alimentary system; eye; nervous system; and reproductive system. Orthologous to human CTDSPL (CTD small phosphatase like).
