Ctdsp2 Gene Summary [Mouse]
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 central nervous system; early conceptus; genitourinary system; integumental system; and respiratory system. Orthologous to human CTDSP2 (CTD small phosphatase 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Ctdsp2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
