The protein encoded by GNE is a bifunctional enzyme that initiates and regulates the biosynthesis of N-acetylneuraminic acid (NeuAc), a precursor of sialic acids. Additionally we are shipping GNE Antibodies (70) and GNE Kits (3) and many more products for this protein.

The results demonstrate a critical novel role for gne in embryonic development and particularly in myofiber development, muscle integrity and activity.
Two most common mutations including c.2179G>A(p.V727M) and c.1853T>C(p.I618T) were detected in majority of tested GNE myopathy cases. c.920T>G(p.F207C) and c.1664C>T(p.A555V) were next common variants detected. Total of 4 novel variants were identified including c.95T>C(p.M32T), c.490_491dupAT, c.920T>G(p.F307C) and c.1822C>A(p.P608T). Rajsthani people share this gene with the founder mutation of Roma.
The differential proteome profile of HEK293 cells overexpressing pathologically relevant recombinant mutant GNE protein (D207V and V603L) was analyzed. Significant reduction in mRNA and protein levels of PrdxIV was observed in GNE mutant cell lines compared with vector control. The ER redox state was significantly affected due to reduced normal GNE enzyme activity.
Thirty-five different mutations in the GNE gene were recorded in a cohort of GNE-myopathy patients from the Indian subcontinent. p.Val727Met is likely to be a founder mutation of Indian subcontinent.
the interaction between GNE and alpha-actinin 1 (show ACTN1 Proteins) and alpha-actinin 2 (show ACTN2 Proteins) occur at different sites in the alpha-actinin (show ACTN1 Proteins) molecules and that for alpha-actinin 2 (show ACTN2 Proteins) the interaction site is located at the C-terminus of the protein.
the half-life of the M743T variant is two times longer than for the wild-type GNE protein. This study provides that the balance of phosphorylation and O-GlcNAcylation is decisive involved in efficiency and regulation of GNE.
The results of this study widen the spectra of mutations to copy number variations encompassing 5'UTR, underscoring the pivotal role of the hGNE1 transcript in GNE myopathy.
the complex crystal structure of the N-terminal epimerase part of human GNE shows a tetramer in which UDP binds to the active site and CMP (show MATN1 Proteins)-Neu5Ac binds to the dimer-dimer interface.
This study confirms that c.2228T>C (p.M743T) is the most prevalent disease-causing variant in the non-Jewish Persian population, but other GNE variants can cause GNE myopathy in this population.
examined the consequences of the mutated GNEM743T enzyme in myoblasts cultures, depicted by the pattern of central signaling proteins of the PI3K (show PIK3CA Proteins)/AKT (show AKT1 Proteins), BCL2 (show BCL2 Proteins) and ARTS/XIAP (show XIAP Proteins) pathways
Novel GNE mutations were linked to GNE myopathy in patients from mainland China.
GNE is a master regulator of sialic acid synthesis in the vertebrates. (Review)
Analysis of differential Gne transcript expression of the two splice variants, Gne1 and Gne2.
GNE is strongly involved in cardiac tissue and skeletal muscle early survival and organization.
Our findings suggest that GNE expression is induced when myofibers are damaged or regenerating, and that GNE plays a role in muscle regeneration.
sialic acid biosynthesis is involved in proliferation and expression of GNE
inactivation of the UDP-GlcNAc (show B3GNT2 Proteins) 2-epimerase (show RENBP Proteins) by gene targeting causes early embryonic lethality in mice, thereby emphasizing the fundamental role of this bifunctional enzyme and sialylation during development
compared the amount of membrane-bound sialic acids of wildtype mice with those of heterozygous GNE-deficient mice
Mutations in the Gne enzyme, which encode the rate-limiting enzyme in sialic acid biosynthesis, are causative of distal myopathies with rimmed vacuoles or hereditary inclusion body myopathy.
The protein encoded by this gene is a bifunctional enzyme that initiates and regulates the biosynthesis of N-acetylneuraminic acid (NeuAc), a precursor of sialic acids. It is a rate-limiting enzyme in the sialic acid biosynthetic pathway. Sialic acid modification of cell surface molecules is crucial for their function in many biologic processes, including cell adhesion and signal transduction. Differential sialylation of cell surface molecules is also implicated in the tumorigenicity and metastatic behavior of malignant cells. Mutations in this gene are associated with sialuria, autosomal recessive inclusion body myopathy, and Nonaka myopathy. Alternative splicing of this gene results in transcript variants encoding different isoforms.
