Protein

UTP--glucose-1-phosphate uridylyltransferase

Gene

UGP2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Plays a central role as a glucosyl donor in cellular metabolic pathways.

Caution

The human genome was initially thought to contain 2 genes for UTP--glucose-1-phosphate uridylyltransferase: UGP1 and UGP2. However, the sequence defined as UGP1 (PubMed:8354390) probably does not exist and corresponds to UGP2.1 Publication

Catalytic activityi

UTP + alpha-D-glucose 1-phosphate = diphosphate + UDP-glucose.
