Summary: This gene belongs to a family of glycohydrolytic enzymes which remove sialic acid residues from glycoproteins and glycolipids. Expression studies in COS7 cells confirmed that this gene encodes a functional sialidase. Its cytosolic localization was demonstrated by cell fractionation experiments. [provided by RefSeq, Jul 2008]
Gangliosides, sialic acid-containing glycosphingolipids, are located at the surface of the cell membrane with the hydrophilic oligosaccharide chain extending into the extracellular space. From the Cambridge …
People with sialic acid storage disease have signs and symptoms that may vary widely in severity. This disorder is generally classified into one of three forms: infantile free sialic acid storage disease, Salla disease, and intermediate severe Salla disease. 2020-03-17 · Sialic acids are a heterogeneous group of monosaccharides that play key roles in human glycobiology. This Review describes derivatization strategies that allow the straightforward analysis of Sialic acid binding was observed in structures crystallized at both pH 8.0 (PDB 6QU6) and pH 4.0 (PDB 6QU8).
9-O-Acetylation is known to be selectively expressed on gangliosides in melanoma cells and on N-linked chains in hepatocytes. Sialic acid storage disease is an inherited disorder that primarily affects the nervous system. People with sialic acid storage disease have signs and symptoms that may vary widely in severity. This disorder is generally classified into one of three forms: infantile free sialic acid storage disease, Salla disease, and intermediate severe Salla disease.
2021-02-24 · Sialic acid metabolism involves a series of enzymes responsible for the synthesis of CMP-sialic acid, which is the donor later used by different sialyltransferases to add sialic acids to an
Sialic acid storage disease is an inherited disorder that primarily affects the nervous system. People with sialic acid storage disease have signs and symptoms that may vary widely in severity. This disorder is generally classified into one of three forms: infantile free sialic acid storage disease, Salla disease, and intermediate severe Salla disease.
Siglecs (Sialic acid-binding immunoglobulin-type lectins) are cell surface proteins that bind sialic acid. They are found primarily on the surface of immune cells and are a subset of the I-type lectins. There are 14 different mammalian Siglecs, providing an array of different functions based on cell surface receptor-ligand interactions.
Diseases. Sialic acids are related to several different diseases observed in humans. Salla disease. Salla disease is an extremely rare illness which is considered the mildest form of the free sialic acid accumulation disorders though its childhood form is considered an aggressive variant and people who suffer from it have mental retardation.

The sialic acids (N -acylneuraminic acids) are a family of 2-keto-3-deoxy-5-aminononulopyranosic sugars that are differentiated by their types of N + O acylations, the most common of which is N -acetylneuramic acid (NeuNAc). The ability to grow on sialic acids appears to be widespread among gram-positive bacteria.

The term sialic acid is used to describe derivatives of neuraminic acid, where the amino group of neuraminic acid is substituted by either an acetyl or glycolyl group. The unique structural features of the molecule, which includes a negative charge owing to a carboxyl group, enables it to play a rol …
They are widely distributed in nature, mainly Sialic acid is a sugar produced when lysosomes break down certain sugar- containing proteins (glycoproteins) or fats (glycolipids). In sialic acid storage disorders, Sialic acids are a class of alpha-keto acid sugars with a nine-carbon backbone. The term "sialic acid" (from the Greek for saliva, σίαλον - síalon) was first Mar 8, 2021 Sialic acid-Dependent Binding and Viral Entry of SARS-CoV-2.
