UniProtKB - Q8CGR7 (UPP2_MOUSE)
Protein
Uridine phosphorylase 2
Gene
Upp2
Organism
Mus musculus (Mouse)
Status
Functioni
Catalyzes the reversible phosphorylytic cleavage of uridine and deoxyuridine to uracil and ribose- or deoxyribose-1-phosphate (PubMed:14715930).
The produced molecules are then utilized as carbon and energy sources or in the rescue of pyrimidine bases for nucleotide synthesis (Probable).
Curated1 PublicationCatalytic activityi
- EC:2.4.2.31 Publication
Activity regulationi
A conditional disulfide bridge can form within the protein that dislocates a critical phosphate-coordinating arginine Arg-100 away from the active site, disabling the enzyme.By similarity
Kineticsi
- KM=241.7 µM for uridine1 Publication
: UMP biosynthesis via salvage pathway Pathwayi
This protein is involved in step 1 of the subpathway that synthesizes uracil from uridine (phosphorylase route).1 Publication This subpathway is part of the pathway UMP biosynthesis via salvage pathway, which is itself part of Pyrimidine metabolism.View all proteins of this organism that are known to be involved in the subpathway that synthesizes uracil from uridine (phosphorylase route), the pathway UMP biosynthesis via salvage pathway and in Pyrimidine metabolism.

Tissue specificityi
Liver specific.1 Publication
Inductioni
Directly up-regulated in liver by HNF-4-alpha (HNF4A) binding to the promoter. May also be indirectly regulated by signaling via various orphan nuclear receptors. Strongly up-regulated by a liver X receptor (LXR) agonist. Slightly up-regulated by a pregnane X receptor (PXR) agonist. Strongly repressed by a peroxisome proliferator-activated receptor alpha (PPAR-alpha) agonist. Slightly repressed by a farnesoid X receptor (FXR) agonist. Shows a diurnal expression pattern with peak levels 12 hours after light onset and lowest levels 0 hours after light onset.1 Publication
