Summary
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. Is active in cytosol. Is expressed in early embryo; extraembryonic ectoderm; nervous system; and sensory organ. Used to study mitochondrial DNA depletion syndrome 1. Orthologous to human UPP1 (uridine phosphorylase 1). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
