Protein

Bifunctional UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase

Gene

Gne

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Regulates and initiates biosynthesis of N-acetylneuraminic acid (NeuAc), a precursor of sialic acids. Required for normal sialylation in hematopoietic cells By similarity. Sialylation is implicated in cell adhesion, signal transduction, tumorigenicity and metastatic behavior of malignant cells. Plays an essential role in early development.By similarity1 Publication

Catalytic activityi

UDP-N-acetyl-alpha-D-glucosamine + H2O = N-acetyl-D-mannosamine + UDP.
ATP + N-acyl-D-mannosamine = ADP + N-acyl-D-mannosamine 6-phosphate.

Enzyme regulationi

Allosterically regulated; feedback inhibited by cytidine monophosphate-N-acetylneuraminic acid (CMP-Neu5Ac), the end product of neuraminic acid biosynthesis. Activity is dependent on oligomerization. The monomer is inactive, whereas the dimer catalyzes only the phosphorylation of N-acetylmannosamine; the hexamer is fully active for both enzyme activities By similarity. Up-regulated after PKC-dependent phosphorylation.By similarity
