UDP-glucose 6-dehydrogenase
(Redirected from UGDH)
UDP-glucose 6-dehydrogenase is a cytosolic enzyme that in humans is encoded by the UGDH gene.[5][6][7]
The protein encoded by this gene converts UDP-glucose to UDP-glucuronate and thereby participates in the biosynthesis of glycosaminoglycans such as hyaluronan, chondroitin sulfate, and heparan sulfate. These glycosylated compounds are common components of the extracellular matrix and likely play roles in signal transduction, cell migration, and cancer growth and metastasis. The expression of this gene is up-regulated by transforming growth factor beta and down-regulated by hypoxia.[7]
This enzyme participates in 4 metabolic pathways: pentose and glucuronate interconversions, ascorbate and aldarate metabolism, starch and sucrose metabolism, and nucleotide sugars metabolism.
Loss of UGDH has recently been implicated in epileptic encephalopathy in humans[8]
Nomenclature
