additional information
malfunction
the absence of Neu1 results in the increased sialylation of the cell surface proteins, probably affecting multiple receptors for phagocytosis. Macrophages from the Neu1-deficient mice show increased sialylation and impaired phosphorylation of FcgammaRas well as markedly reduced phosphorylation of Syk kinase in response to treatment with immunoglobulin G-opsonized beads
malfunction
-
mutations of residues expected to interact directly with the sialic acid N5-acetyl (A160, M87, I105) and C7-C9 glycerol side-chain (E113, Y179, Y181) reduce enzymatic activity. Truncations at the N- or C-terminus of more than 10 residues abolish enzyme activity
malfunction
-
neuraminidase insertion mutant virus shows increased particles formation, in pseudotyped particles system, activity compared to the wild-type virus. Compared with the wild-type AH N1, from A/California/05/2009/H1N1, the wild-type 09N1 exhibits higher neuraminidase activity and releases more pseudoparticles. Deletion/insertion of the 09s60 segment does not alter this relationship. The infectivity of pseudoparticles harboring neuraminidase in combination with the hemagglutinin from HPAI H5N1 (AH H5) is decreased by insertion of 09s60 into AH N1 and is increased by deletion of 09s60 from 09N1, the mutation also alters the oligomeric structure, overview; neuraminidase insertion mutant virus shows increased particles formation, in pseudotyped particles system, activity compared to the wild-type virus.

metabolism
-
NEU4 long is a downstream component of the PI3K/Akt signaling pathway required for retinoic acid-induced differentiation of neuroblastoma SK-N-BE cells
metabolism
-
NEU3 regulates the detergent resistant membranes ganglioside content and is as a modulator of Akt phosphorylation
physiological function
-
trans-sialidase plays a key role in the recognition and invasion of host cells and in enabling the parasite to escape the human immune response
physiological function
-
the NanA neuraminidase of Streptococcus pneumoniae is involved in biofilm formation
physiological function
-
the NanI and NanJ sialidases of Clostridium perfringens are not essential for virulence
physiological function
treatment of the cells with purified mouse Neu1 reduces surface sialylation and restores phagocytosis. Cell surface Neu1 activates the phagocytosis in macrophages and dendritic cells through desialylation of surface receptors, thus, contributing to their functional integrity
physiological function
-
neuraminidase enhances the initial steps of human T-cell leukemia virus type 1 replication
physiological function
-
attachment of Newcastle disease virus to the host cell is mediated by the haemagglutinin-neuraminidase, a multifunctional protein that has receptor recognition, neuraminidase and fusion promotion activities. Multiple regions of the haemagglutinin-neuraminidase protein globular head are important for fusion promotion, and wild-type levels of neuraminidase activity are not absolutely required for viral infection
physiological function
-
the middle region of the HPIV2 F protein contains the site(s) that determines its specificity for the HPIV2 hemagglutinin-neuraminidase protein
physiological function
-
the enzyme plays a pivotal role in bacterial proliferation
physiological function
-
the proline-rich region of NEU4 long can enhance cell proliferation and retinoic acid-induced neuronal differentiation and it is also involved in NEU4 interaction with Akt, as well as in substrate recognition, modifying directly or through the interaction with other protein(s) the enzyme specificity toward sialylated glycoprotein(s)
physiological function
-
isoform NEU1 restrains the endothelial migratory response to wounding
physiological function
the enzyme contributes to the virulence of Treponema denticola. The enzyme protects Treponema denticola from serum killing by preventing the deposition of membrane attack complexes on the bacterial cell surface
physiological function
