Gene: UPP1 (uridine phosphorylase 1) Homo sapiens
Symbol: UPP1
Name: uridine phosphorylase 1
Description: The 2 known types of pyrimidine nucleoside phosphorylases, uridine phosphorylase (UP; EC and thymidine phosphorylase (TP; EC, in the presence of orthophosphate, catalyze the reversible phosphorolysis of uridine and thymidine or deoxyuridine, respectively, to free bases and ribose-1-phosphate or deoxyribose-1-phosphate. Pyrimidine nucleoside phosphorylases can add ribose or deoxyribose to pyrimidine bases to form nucleosides that can be incorporated into RNA or DNA (Watanabe and Uchida, 1995 [PubMed 7488099]).[supplied by OMIM, Aug 2009]
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: OTTHUMP00000159566; OTTHUMP00000208692; UDRPASE; UP; UPASE; UPase 1; UPP; urdPase 1
