UAP1 — UDP-N-acetylglucosamine pyrophosphorylase 1

UAP1 belongs to a gene co-expression module in 6 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

Function

Catalyzes the last step in biosynthesis of uridine diphosphate-N-acetylglucosamine (UDP-GlcNAc) by converting UTP and glucosamine 1-phosphate (GlcNAc-1-P) to the sugar nucleotide. Also converts UTP and galactosamine 1-phosphate (GalNAc-1-P) into uridine diphosphate-N-acetylgalactosamine (UDP-GalNAc). In addition to its role in metabolism, acts as a regulator of innate immunity in response to virus infection by mediating pyrophosphorylation of IRF3: catalyzes pyrophosphorylation of IRF3 phosphorylated at 'Ser-386' by TBK1, promoting IRF3 dimerization and activation, leading to type I interferon responses. Isoform AGX1 has 2 to 3 times higher activity towards galactosamine 1-phosphate (GalNAc-1-P). Isoform AGX2 has 8 times more activity towards glucosamine 1-phosphate (GlcNAc-1-P)
