  • 功能：
    Exo-alpha-sialidase that catalyzes the hydrolytic cleavage of the terminal sialic acid (N-acetylneuraminic acid, Neu5Ac) of a glycan moiety in the catabolism of glycolipids, glycoproteins and oligosacharides. Efficiently hydrolyzes gangliosides including alpha-(2->3)-sialylated GD1a and GM3 and alpha-(2->8)-sialylated GD3. Hydrolyzes poly-alpha-(2->8)-sialylated neural cell adhesion molecule NCAM1 likely at growth cones, suppressing neurite outgrowth in hippocampal neurons. May desialylate sialyl Lewis A and X antigens at the cell surface, down-regulating these glycan epitopes recognized by SELE/E selectin in the initiation of cell adhesion and extravasation. Has sialidase activity toward mucin, fetuin and sialyllactose.

    1. The most potent compound tested targeted the human Neu4 isoenzyme, and was able to substantially reduce the rate of cell migration. We found that the lateral mobility of integrins was reduced by treatment of cells with Neu3, suggesting that Neu3 enzyme activity resulted in changes to integrin-co-receptor or integrin-cytoskeleton interactions PMID: 27344026
    2. The silencing or chemical inhibition of NEU4 changes the entire glycosylation pattern of proteins and lipids, making it more similar to that of differentiated GBM cells and drastically reduces GSCs survival. PMID: 25144716
    3. The results demonstrate that the proline-rich region can also enhance cell proliferation and retinoic acid (RA)-induced neuronal differentiation and it is also involved in NEU4 interaction with Akt. PMID: 24030392
    4. Overexpression of NEU4 is associated with neuroblastoma. PMID: 22287118
    5. NEU4 is involved in regulation of neuronal function by polySia degradation in mammals. PMID: 22393058
    6. NEU4 plays an important role in control of sialyl Lewis antigen expression and its impairment in colon cancer PMID: 21521691
    7. The NEU4 long form localizes in mitochondria, while the short form is also associated with the endoplasmic reticulum. PMID: 19797320
    8. The NEU4 gene, identified by searching sequence databases for entries showing homologies to the human cytosolic sialidase NEU2, maps in 2q37 and encodes a 484-residue protein. PMID: 14962670
    9. Neu4 is a novel human lysosomal lumen sialidase PMID: 15213228
    10. Data show that the differentiation of monocytes into macrophages is associated with regulation of the expression of at least three distinct cellular sialidases, Neu1, 3, and 4, with specific up-regulation of the enzyme activity of only Neu1. PMID: 15885103
    11. related to malignancy and may be potential targets for cancer diagnosis and therapy PMID: 18651674
