Rate-limiting Description

"Uridine diphosphoglucose dehydrogenase (UDPGD) activity is the irreversible, rate-limiting step in the production of UDP-glucuronate, an essential monosaccharide in the synthesis of HA." (8471533)

Regulatory Information

Upstream transcription factor


Regulatory type


transcriptional factor;Sp1(6667)

"Analysis of human UDP-glucose dehydrogenase gene promoter: identification of an Sp1 binding site crucial for the expression of the large transcript." (16002992#16495656)

key enzyme;

"To investigate the mechanisms by which cytokines and 17beta-oestradiol (17beta-E2) modulate gene expression and activity of uridine diphosphoglucose dehydrogenase (UGDH), a key enzyme of GAG synthesis in articular chondrocytes." (18238796)

transcriptional level;

"UGDH core promoter has a role in up- and down-regulation of UGDH after TGF-beta stimulation and in hypoxic conditions" (12682078)

transcriptional level;

"Our results indicate that the region from nucleotide position -486 to -632 relative to the start of the small transcript contains positive regulatory elements that contribute to gene expression." (16002992)

transcriptional level;

"report the presence of an inhibitory cis-element in the distal region of the UGDH promoter that interacts with putative transcriptional repressors for the negative regulation of the UGDH gene" (16495656)
