  • Target

    • Function

      Uridine diphosphatase (UDPase) that promotes protein N-glycosylation and ATP level regulation. UDP hydrolysis promotes protein N-glycosylation and folding in the endoplasmic reticulum, as well as elevated ATP consumption in the cytosol via an ATP hydrolysis cycle. Together with CMPK1 and AK1, constitutes an ATP hydrolysis cycle that converts ATP to AMP and results in a compensatory increase in aerobic glycolysis. Also hydrolyzes GDP and IDP but not any other nucleoside di-, mono- or triphosphates, nor thiamine pyrophosphate. Plays a key role in the AKT1-PTEN signaling pathway by promoting glycolysis in proliferating cells in response to phosphoinositide 3-kinase (PI3K) signaling.
    • Tissue specificity

      Expressed in adult liver, kidney, prostate, testis and colon. Much weaker expression in other tissues.
    • Pathway

      Protein modification; protein glycosylation.
    • Sequence similarities

      Belongs to the GDA1/CD39 NTPase family.
    • Post-translational

      N-glycosylated; high-mannose type.
    • Cellular localization

      Endoplasmic reticulum lumen.
