Enables several functions, including identical protein binding activity; magnesium ion binding activity; and pyrimidine deoxyribonucleotide binding activity. Involved in nucleoside triphosphate catabolic process. Located in cytosol. Is expressed in several structures, including alimentary system; brain ventricular layer; lung; orbito-sphenoid; and vertebral axis musculature. Orthologous to human DCTPP1 (dCTP pyrophosphatase 1).
