role of splice variant GNE1 in basic supply of cells with sialic acids, whereas GNE2 and GNE3 may have a function in finetuning of the sialic acid pathway. No significant differences in activities of splice variants mGNE 1 and mGNE2 |

GNE interacts with proteins involved in the regulation of development, e.g. the transcription factor promyelotic leukemia zinc finger protein, which might play a crucial role in the hereditary inclusion body myopathy. GNE is regulated by a variety of biochemical means, including tetramerization promoted by the substrate UDP-GlcNAc, phosphorylation by protein kinase C and feedback inhibition by CMP-Neu5Ac, which is defect in the human disease sialuria. Multienzyme complexes of GNE with the other enzymes of the sialic acid biosynthesis pathway, either close to the Golgi CMP sialic acid transporter or in particular with the nuclear localized CMP-sialic acid synthetase, are possible |
