Sialic acid synthesis in animals takes place primarily in the cytosol and involves four enzymes participating in a five-step process (see Figure 3).The dual activity enzyme UDP-GlcNAc 2-epimerase/ ManNAc-6-kinase (gene symbol GNE) converts the starting substrate uridine 5'-diphosphate-N-acetyl-D-glucosamine (UDPGlcNAc) to N-acetyl-D-mannosamine (ManNAc) with removal of the UDP moiety and

Initial attachment on cells through primary receptor binding is usually For example, influenza viruses bind to receptors containing sialic acid on the cell surface CONDENSED WORK PLAN: For identification of novel receptors, we plan to of cellular receptor distribution on cells and tissues, iv) that sialic acid containing In a series of publications, we have reported that this virus uses sialic acid as a cellular receptor.

The sialic acid dependence of MAG inhibition was challenged by the recent identification of the Nogo-66 receptor (NgR1) as a high-affinity MAG receptor that supports binding in a sialic acid-independent manner (Domeniconi et al., 2002; Liu et al., 2002).

A new SELEX scheme is proposed for the selection of aptamers targeting a specific epitope of a native protein. Anti-sialic acid receptor (SAR) aptamers that inhibit H1 hemagglutination at a low picomole dose are selected accordingly. The interaction between influenza virus hemagglutinin and its cell-surface receptor, 5-N-acetylneuraminic acid (sialic acid), was probed by the synthesis of 12 sialic acid analogs, including derivatives at the 2-carboxylate, 5-acetamido, 4-, 7-, and 9-hydroxyl, and glycosidic positions.
The distinct preference for either of the two major types of sialic acid is an important determinant of the influenza virus host range (11). Whether MuV uses a particular sialylated sugar structure as a receptor is unknown. Sialic acid-binding immunoglobulin-like lectin (Siglecs), the receptor of Sia, has been well studied recently [ 12 ].
Authors have demonstrated that B cell receptor-associated protein 31 (BCAP31) One of the possible tools in the efficient diagnosis is sialic acid-molecularly
I have one question about the sialic acid receptors. My understanding is that the avian influenza virus has a preferential binding to alpha(2,3) linked sialic acids, but when it becomes pandemic, in order to transmit from human to human, it can also bind to alpha(2,6) linked sialic acids. Sialic acid recognition remains an interesting and challenging target in molecular receptor design. Herein, we report a series of benzoboroxole-based receptors in which cationic hydrogen-bond donors have been introduced and shown to promote multipoint sialic acid recognition.

Sialic acid-binding immunoglobulin-like lectin (Siglecs), the receptor of Sia, has been well studied recently [ 12 ]. The Sia-Siglec axis of some immune cells including dendritic cells (DCs), treg cells, B lymphocytes and monocytes is closely related to the inflammation in atherosclerosis [ 13, 14, 15 ]. Most sialic acids which are recognized as receptors are terminal sialic acids attached to a penultimate galactose by either α2,3-linkage or α2,6-linkage.

earlier studies have shown that they have receptors for both avian (sialic acid-alpha-2,3-terminal saccharides (SA- alpha-2,3)) and swine/human (SA-alpha-2,6) influenza viruses in the upper
Human Siglec‐5, encoded by SIGLEC5 gene, has four extracellular Ig‐like domains and a cytosolic inhibitory motif. We discovered human Siglec‐14 with three Ig‐like domains, encoded by the SIGLEC14 gene, adjacent to SIGLEC5. Using a lectin-based staining based on specific agglutinins, we found that, in addition to the presence of sialic acid alpha2,3-galactose (SAalpha2,3-gal) linked receptors, there are abundant sialic acid alpha2,6-galactose (SAalpha2,6-gal) linked receptors in quail trachea and intestine. The receptor-interacting site is conserved in all coronavirus S glycoproteins that engage 9- O -acetyl-sialogycans, with an architecture similar to those of the ligand-binding pockets of “essential arginine” critical for sialic acid recognition in both Siglec-14 and Siglec-5 is present in humans but mutated in almost all great ape alleles.—Angata, T., Hayakawa, T., Yamanaka, M., Varki, A., Nakamura, M.
