Upp1 - uridine phosphorylase 1

Enables deoxyuridine phosphorylase activity; thymidine phosphorylase activity; and uridine phosphorylase activity. Involved in pyrimidine nucleoside monophosphate metabolic process and uridine catabolic process. Acts upstream of or within pyrimidine nucleotide metabolic process and uridine metabolic process. Located in cytosol. Is expressed in early embryo; extraembryonic ectoderm; nervous system; and sensory organ. Orthologous to human UPP1 (uridine phosphorylase 1).
