It is a component the cell plasma membrane which modulates cell signal transduction events. Gangliosides have been found to be highly important in immunology. Ganglioside GD2 carries a net-negative charge at pH 7.0 and is acidic. Gangliosides can amount to 6% of the weight of lipids from brain, but they are found at low levels in all animal tissues. The GD2 ganglioside is a cell surface component that appears on the surface of metastatic melanoma cells and is a marker for the progression of the disease.(PubMed ID 9216084) Gangliosides are glycosphingolipids. There are four types of glycosphingolipids, the cerebrosides, sulfatides, globosides and gangliosides. Gangliosides are very similar to globosides except that they also contain N-acetyl neuraminic acid (NANA) in varying amounts. The specific names for the gangliosides provide information about their structure. The letter G refers to ganglioside, and the subscripts M, D, T and Q indicate that the molecule contains mono-, di-, tri and quatra-sialic acid. The numbered subscripts 1, 2 and 3 refer to the carbohydrate sequence that is attached to the ceramide. In particular, 1 stands for GalGalNAcGalGlc-ceramide, 2 stands for GalNAcGalGlc-ceramide and 3 stands for GalGlc-ceramide. Deficiencies in lysosomal enzymes that degrade the carbohydrate portions of various gangliosides are responsible for a number of lysosomal storage diseases such as Tay-Sachs disease, Sandhoff disease, and GM1 gangliosidosis. The carbohydrate portion of the ganglioside GM1 is the site of attachment of cholera toxin, the protein secreted by Vibrio cholerae.
