GeneCards Summary for UAP1 Gene

UAP1 (UDP-N-Acetylglucosamine Pyrophosphorylase 1) is a Protein Coding gene. Diseases associated with UAP1 include hepadnavirus infection. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein. GO annotations related to this gene include carbohydrate binding and UDP-N-acetylglucosamine diphosphorylase activity. An important paralog of this gene is UAP1L1.

UniProtKB/Swiss-Prot for UAP1 Gene
